the problem has persisted for some time, but I do not remember if it worked well in an old Chrome version.

Able to reproduce this issue on Mac 10.12.6, Win-10 and Ubuntu 14.04 using chrome reported version #63.0.3239.132, latest stable #64.0.3282.168 and latest canary #66.0.3347.0.
This is a non-regression issue as it is observed from M60 old builds. 

Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

#Unify case: 17748924

On of our enterprise/EDU customer reports that pinned tabs on chrome browser will be cleared, when doing some work. 
The following steps are the reproduce procedure 

My test environment: 
Windows 10 (64 bit) and Chrome browser Ver 71.0.3578.98 

1. Open Chrome browser and pin some tabs. 
2. Close Chrome browser and open it again, You will see the pinned tabs still remain.(this is expected behavior) 
3. Open a web page such as "https://news.google.com" and left click "Hyper Link" on the web page with "open in new window"　option. 
4. At this time , 2 chrome windows are opened, (Original one and new one.) then, Close the original chrome windows . it means that only the new chrome window remain on desktop. 
5. Close the new chrome window. (it means there are no chrome windows on desktop.) 
6. Open chrome browser from it's desktop shortcut icon. 
7. you will see the pinned tabs disappear from bookmark bar. 


[Troubleshoot] 

In my understanding, this "pinned tab" function is using a similar mechanism with "startup: Continue where you left off" setting on chrome browser. 
last session information (including tab information) will be written on the following local file. 
　C:\user\user_name\AppData\Local\Google\Chrome\User Data\profile_name\Current Session 

Then, I am guessing that "step 5" and "step 6" will override \Current Session file and it causes this issue. 


[Question] 

Is this an expected behavior or bug ? Can we have this fix any time soon if it is considered as a bug?

@robliao, @pkasting

If this is indeed considered as a bug that we should fix, could you find some resource to work on it? 

Thank you. 

This is be design. We experimented with all sorts of different options, but this is what made the most sense.

Comment 10 is not this bug, but rather bug 431609.  Neither one of these is WontFix.  This one is a pure bug.  Bug 431609 is more "what was designed originally" but we have a new design on the bug that should address it (see comment 9 and comment 26 on that bug).

Isn't this the same as bug 431609? I could be reading it wrong, but isn't step 4 closing the window with pinned tabs while another window is still open?

Yes, in comment 10, which is why I said comment 10 is bug 431609 and not this bug.  This bug is described in comment 0: if Chrome opens via a direct URL link, any saved pinned tabs will be lost, because the session will get overwritten.

I have checked the reproduce procedure again.
I found that "step 5" and "step 6" are not nessesary to reproduce this issue.

-------------
1. Open Chrome browser and pin some tabs. 
2. Close Chrome browser and open it again, You will see the pinned tabs still remain.(this is an expected behavior) 
3. Open a web page such as "https://news.google.com" and left click "Hyper Link" on the web page with "open in new window"　option. 
4. At this time , 2 chrome windows are opened, (Original one and new one.) then, Close the original chrome windows . it means that only the new chrome window remain on desktop. 
5. Close the new chrome window. (it means there are no chrome windows on desktop.) 
6. Open chrome browser from it's desktop shortcut icon. 
7. you will see the pinned tabs disappear from bookmark bar. 
-------------

↓

-------------
1. Open Chrome browser and pin some tabs.
2. Close Chrome browser and open it again, You will see the pinned tabs still remain.(this is an expected behavior) 
3. Right  Click Hyper link on website or email and open the link with "Open in new windows" option.
4. Close the new window.(this meams that the original chrome window still open.
5. Close the original chrome window.
6. Open chrome browser from it's desktop icon.
-------------

Therefore, I think that this is the same issue as this issue.

OK, well that's interesting.

The steps to reproduce the problem are:
First of all: the condition is that the Chrome Browser is the Defautl Windows Browser in your system (I tested this situation only on a MS Windows System)
1. Open Chrome browser and pin some tabs.
2. Close Chrome browser and open it again, You will see the pinned tabs still remain.(this is an expected behavior) 
3. Close Chrome browser.
4. Now you have received a link to explore, in an email, in a PDF document, etc... (we suppose that it is a secure source). You click over that link.
5. The destination page will be opened in the Chrome browser, because it is the default
6. You will see that the pinned tabs are lost.

I know that, If I have 2 Chrome browsers on desktop, one with pinned tabs and one without, if I close the one without pinned tabs for last, the new opening has lost all the pinned tabs, but I ever thought that this is by design.
My problem is different.
- I closed a pinned browser
- If I reopen it normally, everything is allright
- but if it automatically reopens (because it is the default browser), by linking from an external source, I loose my pinned tabs.
Thank you, Angelo

@19: Right, that's basically the steps in comment 0.

Ugh. It looks like comment 0 and comment 10 describe different scenarios. I was able to repro comment 0. I believe this worked at some point.

I see, you are right.
Comment 10 issue seems to be classified as bug 431609.

 Issue 920138  has been merged into this issue.

I only started using Chrome less than a week ago and have learned about this bug already.  Dismayed to find out it's been an issue for at least a year.

@comment 24
me too!
Just restore those frickin' pinned tabs in every frickin' Chrome Window. If I pin something I want it pinned. No matter if I pinned it in Window A or B. After closing A and B and opening a fresh C, restore those pins from A AND B. That's why I PINNED them.
Pin means Pin! Until I click on it and UNPIN!

If anyone needs a new, fresh, clean, empty Chrome process: Add a new menu item --> Open new clean browser window.
Problem fixed!

If a user clicks on an Email link outside Chrome or clicks on Chrome in Start Menu a second time, grab the running Chrome process to open that link. If no Chrome is running, open new Chrome process while restoring the pinned tabs. Because I pinned them. Pin means pin until I unpin!

@25: You are probably describing the similar-but-distinct bug 431609.

You're a funny guy. Originally I came from bug 431609. I'm comment 27 over there. Then, you told me it's this bug 812545.
Now here I am :-)

Sorry, I misunderstood what you were trying to say in comment 25.  Given your description on the other bug, this is the correct one.

In any case, there's plenty of info here on what the bug is, and it's clearly a bug.  So what's really necessary is engineering investment.  If you know people who'd like to contribute to an open-source project, this might be a good place to do it :)
