you didn't actually write the version. What package is it?

This problem started for me on Windows with version 5.0.396.0. 

The bookmark manager never displays any entries and merely flashes like it's updating 
something. It consumes a large amount of CPU. I let it run for an hour hoping it 
would eventually display something but it never did. Some browser functions are 
impaired while this is happening, like you can't do an "About Google Chrome". If you 
close the errant tab, things go back to normal. 

I have a large amount of bookmarks (around a 1000 or more). 

Chromium	6.0.400.0 (Developer Build 46805) Ubuntu
WebKit	533.9
V8	2.2.8
User Agent	Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.9 (KHTML, 
like Gecko) Chrome/6.0.400.0 Safari/533.9
Command Line	 /usr/lib/chromium-browser/chromium-browser

I am seeing exactly the same behaviour on Ubuntu 10.04 32bit.

You click on the bookmark manager and it crashes the new tab it opens, and makes the 
browser effectively unresponsive until you can kill that tab.

Now I have another bookmark extension which is working perfectly, and I'm having to 
use that to look at my bookmarks. The extension is:
	
Incredible StartPage - Productive Start Page for Chrome! - Version: 0.7.1
A new, customizable start page for Chrome. Easily find your favorite bookmarks and 
closed tabs. Take notes as you browse.
Disable - Uninstall - Options   Allow in incognito

It was the past few versions. Turns out entering chrome://bookmarks in the address bar work ok, it's just using the menu that makes it screwy.

I can confirm with my configuration that using the URL chrome://bookmarks it has no 
problems, but clicking on the menu item causes the problems described above. 

I think this should now be marked as confirmed, as it is 100% reproducible by several 
people.

I'm getting a TOT build to see if I can repro this. It sounds like something is going 
wrong in Browser::ShowSingletonTab

Works on dev builds. I'll get an official build to see if it does something different.

Works on latest nightly as well. We did have some packaging bugs in a few builds so I 
expect you got unlucky and got a build during that time frame.

Have you tested this with a large number of tabs open and a large number of bookmarks?

As mentioned above we both have large amounts of saved bookmarks, which could be a 
contributing factor.

FWIW, I could reproduce this yesterday with a r46824 binary from the buildbot. Today 
however, after having added more bookmarks in the interim and restarting etc., the 
problem is not reproducible anymore.

I have tested this again this morning with this version:
Chromium	6.0.401.0 (Developer Build 46998) Ubuntu
WebKit	533.9
V8	2.2.9
User Agent	Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/533.9 (KHTML, 
like Gecko) Chrome/6.0.401.0 Safari/533.9
Command Line	 /usr/lib/chromium-browser/chromium-browser

It is exactly the same as it has always been, the tab goes wild when you click on the 
menu item. Would a list of extensions that I have installed be of any help in 
diagnosis? Could compiz be a factor in this?

I have just tested this with no extensions enabled, exactly the same.

Still having this issue as of:

I have a fair amount of bookmarks too, and StumbleUpon also adds to your bookmarks so 
maybe that's related.

Another clue: 

The problem had stopped, then I sorted by bookmarks. I also fired up Chrome from a 
computer at another location that is also synced. Now on the original computer, the 
problem has returned. Bookmarks manager just "flashes" without displaying any 
information. Accessing the bookmarks through the button (--bookmark-menu) works. 
Accessing bookmarks from chrome://bookmarks WORKS. Accessing bookmarks through the 
"wrench" does not. I have a large number of bookmarks and a large unsynced-count.

This is still not working.

There are a couple things going on here.

The bookmark manager is a built in extension, called COMPONENT extension. It uses chrome_url_override to override 
chrome://bookmarks/. That means that when we navigate to chrome://bookmarks/ we redirect to chrome-
extension://<bookmark-extension-id>/main.html.

When we open the bookmarks from the menu we follow this redirect before opening a tab. This is so that we can 
reuse any possible open bookmarks tab.

There are two things that can go wrong in two different ways with very different outcome but the UI looks very similar:

1. The bookmarks extension fails to get registered so the url override does not happen. In this case 
chrome://bookmarks/ never finishes loading. This results in a white page and spinner never stops. The CPU should 
not be busy and this should use no memory.

2. The bookmarks extension gets registered correctly and the URL override works but when chrome-
extension://<id>/main.html loads it realizes that chrome.bookmarks is not available and it does a 
window.location.reload(). This results in high CPU and flickering of the page.

I'll make 1 show an error message of some kind and I'll make 2 not reload in case the extension system is not working. 
That should make it easier to track down this bug.

Definitely getting a CPU usage spike.

That is very interesting new information, and I'm also seeing the second example where 
you get a large cpu spike, with difficulty in shutting the tab once you clicked on the 
menu item.

Using 6.0.405.0~svn20100515r47353-0ubuntu1~ucd1~lucid is a big improvement. The 
bookmark manager loads to a point, but no bookmarks appear. chrome://bookmarks still 
works fine.

Chromium	6.0.407.0 (Developer Build 47392) Ubuntu
WebKit	534.0

With the above version it doesn't crash the tab any more, but it doesn't load the 
bookmarks which is a step forward I guess.

I have attached a picture of what I get.

Seems to be fixed using 6.0.407.0~svn20100517r47392-0ubuntu1~ucd1~lucid.
:)

Tested again this morning with the following version , no change. 
6.0.409.0~svn20100519r47612-0ubuntu1~ucd1~lucid

The bookmarked extension works fine, but when I click on the wrench button, it gives 
me the bookmark manager screen, but it is unpopulated. At least the tab going mad has 
stopped.

Do you think this could be linked to a potential conflict with a chromium extension? 

OK, not working for me again.
Now using 6.0.416.0~svn20100526r48240-0ubuntu1~ucd1~lucid

 Issue 44727  has been merged into this issue.

 Issue 44789  has been merged into this issue.

I haven't been able to reproduce this. Can someone provide more details?

When I had this issue I restarted Chrome and the bookmark manager worked again.
I can't reproduce it by now.
The error console was saying: "Bookmarks extension API is not avaiable. main.html:51"
My issue:  http://crbug.com/44807 

And BTW, My OS is Windows, not Linux nor Mac OS as this issue is labeled.

Removing release block until this can be reproduced.  FYI, I can't get it to happen in my mac build of 6.0.422.0.

This issue is always reproducible in my Windows machine.

See here for error messages http://code.google.com/p/chromium/issues/detail?id=44727#c2

As of this mornings testing with the version below, the bookmark manager is working 
as designed again. This is the first version to work properly in Ubuntu Linux since I 
reported the issue.

Chromium	6.0.424.0 (Developer Build 48800) Ubuntu
WebKit	534.1
V8	2.2.14
User Agent	Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.1 (KHTML, 
like Gecko) Chrome/6.0.424.0 Safari/534.1
Command Line	 /usr/lib/chromium-browser/chromium-browser

Bookmark manager is still unpopulated for me as of 6.0.424.0~svn20100603r48800-
0ubuntu1~ucd1~lucid

I've noticed this also happens if you open it from the bookmark bar context menu. 
Going to chrome://bookmarks is the only way I've found that works.

I've also found that after opening the non-functioning bookmark manager, trying to 
load "chrome://bookmarks" in that tab doesn't work.

Is there more information I can give to help track this down?

Xantam: Could you try to remove your Preferences file (after making a backup of 
course)?

OK, I found the chromium directory in ~/.config and renamed it and the bookmark 
manager worked fine. This narrowed it down to something in my profile so I tried 
extensions and I've narrowed it down to the following extension:
https://chrome.google.com/extensions/detail/ahldefgplekckalfcolhhnljbbgaiboc

Disable the extension and the bookmark manager works. Enable it and it doesn't work 
again. Given the extensions I use I didn't expect it to be the result of an extension, 
and I'm not sure how this extension is causing it.

I just noticed this bug.
when to bookmark manager and it was empty
Inspector Element Console show:
Bookmarks extension API is not avaiable

6.0.427.0 (49012) Ubuntu Maverick 64 bits

Build: 6.0.427.0 (49012) Ubuntu Lucid x86-64

I can confirm a similar (or same) problem: Opening bookmark manager shows page 
without any bookmarks, JS console shows: "Bookmarks extension API is not avaiable" 
etc.

After an hour of messing around, here's what I tried and did not work:
1) disabling extensions
2) resetting Preferences via profile directory

On a clean profile (everything removed besides "Bookmarks"), it works.

On a clean profile with everything except "Bookmarks" and "Current Session"/"Current 
Tabs" removed, it does not work.

When I close a few tabs from semi-clean state, suddenly at one point the bookmark 
manager starts working. (does not seem to depend exactly on which tabs I close). If I 
restart and reload the same session, it does not work again.

After I open and navigate some tabs in a working bookmark manager state, it stops 
working again.

(as a note, the huge amount of tabs (101) I have open maxes the process limit on 
startup)

I can reproduce this from a clean install by applying my Session files. If anyone is 
interested, I can send them privately.

I can confirm that that extension is potentially causing the problem on my system as 
well. When it is disabled the bookmark manager works. This is a new phenomenon 
though, as I have tested with all extensions disabled before with no positive effect. 
I will test with this disabled for the rest of the week. 

Is this only an issue with Linux versions?

This error indicates that the renderer is not getting the message ViewMsg_Extension_SetApiPermissions message for some reason:

http://src.chromium.org/cgi-bin/gitweb.cgi?p=chromium.git;a=blob;f=chrome/common/render_messages_internal.h;hb=HEAD#l731

Perhaps it is getting sent, but not in time. @erikkay, mpcomplete, does anyone want to take this bug off arv? It probably isn't his.

I'll take a look.

Thanks to the hint from @41, I believe this is related to process exhaustion.  It appears that there are cases where an extension can get put into a normal renderer process.  In that case, it never gets the extension's permissions, so it doesn't work.  The code here is somewhat complex so I don't have a solution quite yet.

Unfortunately, the real fix for this turned out to be complex, and is too risky for M6.  Punting to M7.

The Bookmark Manager is blank on my build as well. I remove ad blocker and its still showing  up blank.

My Current info:
Google Chrome	6.0.466.0 (Official Build 52279) dev
WebKit	534.3
V8	2.2.23

I just check the Developer Tools and under console 
main.html:1461 Bookmarks extension API is not avaiable
main.html:1474 Uncaught TypeError: Cannot read property 'bookmarkManager' of undefined.

There is a problem in how the processes are spawned/managed in chrome?
Or in the way chrome uses WebKit?

It is easier hitting this behavior after some time that chrome is running and/or if the browser is overloaded. 

Similar issues I think is when we open URLs in tabs that doesn't loads properly the content (hanging in a blank page). Or also the history tab (same issue).

If I kill and rerun chrome, then for a while everything works well.

In my experience, this behavior could hang other applications. For example when I use Mailplane WITH chrome, and chrome starts to behave weirdly, Mailplane hangs in some WebKit code.

BUT, if I find which tab(s) is in some way hanging all the processes, and I kill or close the 'guilty' tab(s), the bookmark manager loads properly. The history tab works well. Tabs resumes to load content.

Or can be a WebKit issue...

Arch-Linux, 32bit

Since some days ago the bookmark manager does not work. The page comes up totally blank. No further problems whatsoever, it's just f****** blank ;) Currently i run build 53633. Under Windows7 Build 53036 still shows the Bookmark Manager. Will try to update there this evening...

compiled build v6.0.477.0, build 53633 under Windows 7: have no problems so far

Sorry, was build 53632 not 53633

 Issue 49485  has been merged into this issue.

I can confirm that when processes are maxed out, sometimes extensions get put into normal renderer processes. This issue not only affects Bookmark Manager, but also other extensions (Google Similar Pages) which also do not work when installed in a lot of tabs (processes maxed) state.

At this point, the Bookmark Manager doesn't work the first time I open it, but the second time I open it it'll work for a while.

"At this point, the Bookmark Manager doesn't work the first time I open it, but the second time I open it it'll work for a while."

The same thing happens over here.

This happens me when I opened a lot of tabs and windows.

sigh.  unfortunately this is too complex to land in m7 at this point.

Same issue here with the blank bookmarks listing. I can access the bookmarks from the bar, but not from the manager.

Same issue here.  It was working only a couple of hours ago.  Any fix here?  I' running the latest de channel version on a Windows 7 machine.

I have it happening for the first time ever - Chrome 6.0.472.55 beta.  WinXP.  

Right-click of the bookmark bar does not work
Spanner does not work
chrome://bookmarks in address bar does not work

@65 - you're likely seeing a different bug.  If the bookmarks bar doesn't work and the wrench menu doesn't work, then something else is going on.  Please file a separate bug, ideally with more information about how you got into this state, etc.

For others, unforunately, there's no workaround to this problem yet.  It turns out to be fairly complex to fix correctly.

For what it is worth, I was seeing this problem, but am no longer.  At least in Chrome 6.0.472.55 beta, for me, it is fixed...

Am using 7.0.517.8 dev.
I see empty chrome:bookmarks, as per Comment 61 by dogantuncer, Aug 19, 2010.

When I look at the Developer Console I see the following:
main.html:1516Bookmarks extension API is not avaiable
main.html:1529Uncaught TypeError: Cannot read property 'bookmarkManager' of undefined

Rob
:)

Per screenshot in comment 61, the blank bookmark manager tab also happens to me in the stable release of 6.0.472.62 (current release), and has persisted since the last stable release.

I also have numerous tabs open (~80 atm), but no add-ins (non-dev version). Bookmarks work for adding; but going to a bookmark only works for those folders displayed on the top bar.

I can reproduce this with 6.0.472.62 (Official Build 59676) on Mac.
Followed the instructions in comment 61.

i also get the blank bookmark manager sometimes but not always :/

 Issue 52790  has been merged into this issue.

 Issue 55546  has been merged into this issue.

EDIT: today the problem occurred again with Google Chrome 7.0.517.8 and many tabs opened. I closed most of the tabs and, not sure if it's related, the bookmark manager started to work again. I reopened all the tabs again and it still works properly.

With previous version of Google Chrome (sorry for not specify the actual release but it's 5.0.*) I had such problem randomly by either go to chrome://bookmarks or click to the Bookmarks Manager. I noticed that by only leaving opened a few tabs (3-4) the problem gone away.
Now, switching to the version 7 of Google Chrome I'm not able to reproduce the problem anymore.

Hope this helps,
Claudio

No time to fix before M8 feature freeze.

Same issue here -- 6.0.472.63 on both Windows 7 64-bit and Windows XP 32-bit.  Using chrome://bookmarks also doesn't work.   Rebooting doesn't solve it.  Tried opening a new instance of chrome with no tabs open at all, also doesn't work.

@broehl.  It sounds like you're seeing a different problem.  The bug as reported is about a random failure that happens when you have a large number of tabs.  If it's not working for you at all in any case, then please file a new bug.

@81, tickets for this problem was marked as duplicates and merged into this (see #44789, #44807).

Getting the same problem with Chromium 7.0.535.0 (60565)on XP 32 bits. Bookmark manager from the wrench menu is blank, using chrome://bookmarks works, though. I don't have any of the extensions mentioned here so far.

@erikkay 78
This is a horrible bug. Are bugs also influenced by the feature freeze?

@82 - I see.  Those may be mistakes.  For those of you who are seeing this problem 100% of the time and with a small number of tabs, I believe you're seeing a different bug.  One other variable to check is how many extensions do you have installed?  One easy way to see if this is the same bug or not is to bring up Chrome's task manager.  When this bug (43448) reproduces, what you'll see is that the bookmark manager tab will be listed together with a different extension or page (as if it was part of the same website or extension).  If you see it standalone and not combined with other pages, then you're hitting a different bug and we should file it separately.  If anybody here is seeing the second behavior, let me know.

@84 - The reason bugs can be influenced by feature freeze is when their size and complexity is such that it's too risky to land after feature freeze.

One more thing you could do to help us diagnose if this is a separate issue.  When you're in this state, right click near the top of the page and select "inspect element" from the context menu.  Then click on the "console" button and report what errors you see.

@85/86 I have no extensions installed, (chrome 6.0.472.62 (Official Build 59676)), but I have a large number of tabs (~30 per window, around 110-140 total). The following occur after inspecting the element, console/errors:

"Bookmark extension API is not avaiable [...] main.html:1523"
"Uncaught TypeError: Cannot read property 'bookmarkManager' of undefined [...] main.html:1536"

Screenshot follows.

I get the same error as 87.

OK.  I don't need any more reports of that particular error.  Let me know if you're getting a different error than "Bookmark extension API is not available".

Fix for me was disabling the 'Send using Gmail" addon/extension as detailed in this bug report:

Fix for me was the same as Marty in comment 90 disabling the 'Send using Gmail" addon/extension solved the issue. (7.0.517.41 beta)

 Issue 60836  has been merged into this issue.

I still have the problem with latest 7.0.517.44 on Windows XP. Entering chrome://bookmarks in the address bar doesn't work also. This results in a white page and spinner never stops. The CPU is not busy, so seems the bookmarks extension fails to get registered. After I disabled a extension: Google Mail Checker - Version: 3.1, it worked,and enable the extension, the bookmark manager broken again. Seems there are some conflict between this extension and bookmark manager.

 Issue 53497  has been merged into this issue.

Failing here in Main.html line 1529:

// Get the localized strings from the backend.
chrome.experimental.bookmarkManager.getStrings(function(data) {
  // The strings may contain & which we need to strip.
  for (var key in data) {
    data[key] = data[key].replace(/&/, '');
  }

Uncaught type error. Cannot read property bookmarkManager of undefined

7.0.517.44 (Official Build 64615)

Here's a clue to the cause:
This issue is directly related to the number of open tab/extension processes (the number of plug-in processes has no effect). 19 processes is the limit, past that (at 20 processes) the bookmark manager stops getting the chrome.bookmarks.

7.0.517.44

The easy way to repeat the error is:
1. Open 21 or more tabs with sites.
2. Open empty tab.
3. Open Bookmarks Manager.

It is failed because of empty tab (or not loaded yet).
If you close empty tab, Bookmarks Manager works.

 Issue 64591  has been merged into this issue.

 Issue 65383  has been merged into this issue.

I reported this as  issue 65383 : blank bookmark manager, which was merged here.

I am not seeing the flickering reported here at  issue 43448 .

I confirm behavior similar to comment 110. I reproduced the problem; then, I killed a few processes with the task manager; then, I was unable to reproduce the problem. NOTE: I did not close the tabs, simply killed the processes.

same here, empty bookmark manager

 Issue 69654  has been merged into this issue.

Hi, the problems with the Bookmark Manager still exist. For example sometimes it just doesn't show up like shown in the attached image. I'm using version 11.0.652.0 but as much as I know the problem has existed since 6.0.x or even earlier version.

Sometimes clearing the cache seems to help, sometimes it doesn't. Some people get it sorted by uninstalling and installing again. Anyway, it's a very annoying issue and has been in existance for a long-long time, so I would think it's about time for Chromium/Google developers to stop being lazy/ignorant and sort it out! ;]

We know this issue still exists, and we plan to fix it.  Unfortunately, the fix is complex and there are currently six bugs blocking it (see the left column).  Please be patient; we'll get there.

In the mean time, we know that this only occurs if the process limit has been reached, either because too many tabs are open or because too many extensions are loaded.  As a workaround, try closing tabs and disabling other extensions until you see fewer than 10 or so processes in about:memory.  (It doesn't need to be that few, but it will help.)

If you still see the problem with very few tabs or extensions, please file it as a separate bug.  I'm updating the title of this bug to be clear.  Thanks!

How about bringing back the old native bookmark manager code (prematurely removed by  Issue 38908  ) as a better workaround until the new bookmark manager is working properly? For me closing most of the tabs is not a viable solution since I usually have more than 50 of them and I don't really want to close them all.

Not sure if this adds to the body of knowledge around this problem or is repetitious.

I just had the exact same problem but with the history tab instead of bookmark manager.

I'm working on a Asus EEE with a 7" display so a screenshot doesn't show everything. Hopefully the info below a) displays better than it does in the message composition window and b) is useful.

(The memory usage of our renderer processes is slightly less accurate when they are sandboxed.)

@creis  How comes this priority 1 bug is blocked on many priority 2 ones. Shouldn't the priority of the others be bumped to reflect the fact that they are blocking a priority 1 issue?

Issue chromium-os:10873 has been merged into this issue.

Let me understand something, please.
Before (some time ago in the development) was 1 process for every tab, now more tabs runs in 1 process (one Renderer process)?

Thank you

Re: comment 133, we have always had a limit on the number of renderer processes we create.  Once that limit is reached, we start to re-use them.  Also, "1 process for every tab" is not accurate.  You can read the details at:

http://www.chromium.org/developers/design-documents/process-models

Also, open a few tabs and then hit Shift+Escape to quickly see which ones are grouped, which is also helpful when trying to get enough processes closed so that you can open the Bookmark Manager. :)

I seem to be also having issues with newly loaded extensions when having a decent amount of tabs open (besides not being able to load the bookmark manager) - does this bug affect *everything* that needs extended permissions?

Prevent unused normal SiteInstances from being used for extensions.
Instead, create a new SiteInstance with the appropriate process type.

Fix landed in r75498.  Should be available in the next Windows Canary build (anything larger than 11.0.672.0).

This doesn't take care of all the refactoring tasks that Erik filed, and I plan to get to those as well.  The fix does ensure that extension pages won't end up in normal processes, though, which prevents the issue with the Bookmark Manager seen here.

Gory details: We were trying to use a mostly-unused SiteInstance for extensions, but the SiteInstance had already been assigned a RenderProcessHost of TYPE_NORMAL.  This meant it was possible for it to get grouped with other normal renderer processes where extensions won't work.  Instead, we can create the SiteInstance earlier, when we know the correct URL and type.

The downside is that it's still possible to create a process and then throw it away if a WebUI URL redirects to an extension URL (e.g., chrome://bookmarks to chrome-extension://).  That's just a little extra work, though-- the page will still work.  Further refactoring should fix that.

@148: The fix for this issue is currently available on the Dev and Beta channels.  It is not yet available on the Stable channel (10.0.648.151), but it should show up in the next update.

The problem disappeared after I re-booted my machine. Not sure if it was due to processing limit or an update that was already downloaded but not in effect until after shutdown. I do online research that spans multiple days and prefer to 'hibernate' rather than shut down (to speed up resumption of my work). When I have several Chrome windows with dozens of tabs open I don't like to shut down. I still think there may be some sort of bug in there but it seems an update already downloaded my contain the fix. I will send an update to this thread if it happens again. Thank you.

Google Chrome    10.0.648.203 (Official Build 78758) dev

I opened over 30 tabs....
