lunastarlit@ Thanks for reporting.

Could you please provide us any sample extension to triage the issue from test team end.

Thanks,

I attach the extension.
I confirmed this problem by clicking mouse wheel on left top chromium icon in this page.

About extenson:
Extension's page is opened instead of originally page when you open a new tab.
If js file is loaded, the message "js is running" is shown in opened extension's page.
If not loaded, the page is blank.

Additiional info:
1) I tried to use this extension on old chrome (chromodo45.9.12.392), then same problem occurred.
2) I tried to use it on other PC (chrome version is same), then i could not find this problem.

The condition which problem occurs was found.
It is whether standard click open a new tab, or not. (target="_blank")
Probably, whether same domain or not is not related.

This doesn't seem like a bug to me, the extension redirects if a request to main_frame is made and the new tab is the active tab.
This means opening a new tab in background (that's what you get using middle click) would result in a redirect.

In your original issue description: do you mean you see test.html loading but test.js not loading? Again I can't reproduce that, please clarify.

Redirection always succeeds.
The problem is that test.js is not loaded.
In devtools' console of test.html shows "Failed to load resource: net::ERR_ADDRESS_UNREACHABLE   chrome-extension://malhjicgjkelgbjpdffjkgihdfahkcmd/test.js".

Case 1
 'a tag' has 'target="_blank"' && use middle click
  -> test.js is not loaded!!

Case 2
 'a tag' has 'target="_blank"' && open new tab from context menu
  -> test.js is loaded. (no problem)

Case 3
 'a tag' do not have target attribute && use middle click
  -> test.js is loaded. (no problem)

Case 4
 'a tag' do not have target attribute && open new tab from context menu
  -> test.js is loaded. (no problem)

Unable to reproduce the issue on windows 7 using chrome version 49.0.2623.112.Not observed any error in console of test.html page.
Please find the attached screen cast and confirm anything missed here.

Request you please try the issue by upgrading chrome to latest stable and update the thread if the issue still persists.

Thanks,

My chrome and os version is same.
I also attach screen shot. (I do not have a tool which save screen to video.)

In latest version, there is no error after reloading page.
Only occur when a new tab is opened.

lazyboy@, it looks like you were looking into this at one point.

Removing from triaging queue,already assigned to an owner.

I got a chance to look at this, it seems opening links that has target="_blank" with middle click makes the new tab end up in the same process as the opener. In this case, it will be the originating site's process, not the extension's process.

 http://crbug.com/23815  seems to be the same bug.

One workaround suggested was to put rel="noreferrer" in that bug [1].

@lunastarlit the root cause of this issue is same as  http://crbug.com/23815 , whatever solution we get to there would apply here.

Marking as duplicate.

Thank you for investigation.

It is difficult to do your suggestion because extension will run on any site.
Also, it may cause other new problems if my extension sets "noreferrer" attribute to all a tags forcibly by injecting a code when a page is loaded.
