Steps to reproduce:

Switched from one open, fully loaded tab to another fully loaded tab.


Actual results:

I had about 5 tabs opened and had been working for awhile with these tabs.  I switched back to one of the tabs that I was working on and the content was suddenly gone and was replaced with a spinner in the middle of the page.  Each tab that I went to after that had the same thing.  Content was gone and was replaced with a spinner.  This has happened to me 3 times over the past couple of days and this behavior is new after installing version 52.  Extensions currently in use are NoScript and AdblockPlus.


Expected results:

Content should have been persistent.  Refresh impossible and browser is practically unresponsive.  Was eventually able to close tabs one at a time with significant delay between pressing close and when the tab actually closed.

Component: Untriaged → Tabbed Browser
Summary: After pages load -- content suddenly disappears on all tabs and is replaced with spinner. FF then slow and practically unresponsive. → [e10s] After pages load -- content suddenly disappears on all tabs and is replaced with spinner. FF then slow and practically unresponsive.
Paging mconley as the resident tab-spinner expert... :-)

This sounds to be like the content process had hung on the main thread.

github, would you be willing to go to about:support, clicking "Copy text to clipboard", and pasting the result in here?

Content Process Sandbox Level: 1
Happened again this morning.  Tabs I had open were a page inside of OUCampus (CMS), Google calendar, and wcupa.edu.  Not sure if this helps, but here is the about support info again since the hanging just occurred.  

Crash report that goes along with it -- 3/16 @ 8:36AM (EST): 
https://crash-stats.mozilla.com/report/index/bp-c0b0f7cc-cf3b-4731-affc-f50a92170316

I'm going to try to do a Firefox refresh and see if that makes a difference.  Let me know if there is any other log info that I can capture for you.

Did the refresh help?

Everything seems okay at the moment.  I'll be using the same set of websites tomorrow morning (EST) pretty heavily so I'll have a better idea if that fixed it.  I'll add a reminder in my calendar to post an update tomorrow early afternoon (EST) so you're not left wondering.  Thanks!

Looking at those stacks in bsmedberg's multistack viewer is pretty illuminating:

The top of the main dump is inside a DLL:

sophos_detoured.dll@0x748eccb3

That sounds like anti-virus to me - specifically, Sophos. Dan, if you disable the "Buffer Overflow Protection System" (which is apparently associated with that DLL), does the problem resolve?

Thanks for the info -- I don't have the ability to change this (managed by group policy I assume).

Dees, do you know if we have contacts at Sophos who we can ask to look into this?

Hoi Gijs. I do happen to have some Sophos contacts based out in NL. I'll email them to you — so that you can reach out to them with myself in cc.

Benjamin, is there some way we can figure out how widespread this issue is?

This is similar to or the same as  bug 1347240. Apparently loading http://www.cic.gc.ca/english/passport/forms/pdf/pptc153.pdf using pdf.js can trigger this.

I suspect there's not a low-effort way of figuring out how often this happens using the data at hand.

We could try blocking their DLL, but I'd want somebody to actually try and install the thing (in a VM!) to reproduce before/after both to make sure the block worked and didn't cause other errors. Carl maybe you'd be interestd?

I'm happy to take a look.

Dan, could you tell me which version/edition of Sophos you're using? I'd like to get a copy and get this to reproduce in a debugger.
Flags: needinfo?(ccorcoran) → needinfo?(github)
Sophos Endpoint Security and Control version 10.7 -- under product information it says v, 10.7.2.49 with detection engine 3.68.0 and detection data 5.38 ; I hope that helps but let me know if you need more/other info.  Thanks!
Does comment 15 give you what you need, ccorcoran?

Mike, yep, and I'll be looking at this today.
Flags: needinfo?(ccorcoran)
I didn't manage to repro it. Windows 7 Ultimate SP1 32-bit, Sophos Endpoint Security (latest version; I didn't manage to get a copy of 10.7 specifically). Firefox release 51, 52, 53. Verified that buffer overrun protection is enabled and sophos_detoured.dll is injected to Firefox, but never managed to get the hang. Tried loading various sites, the mentioned PDF, stressing it a bit, refreshing. I also tried the same steps on Win7 x64 with a 32-bit build of Firefox, also no repro.

Happy to try other ideas...

Anyway tomorrow I'll see how blocking sophos_detoured.dll affects things and report back.
Still no repro, but this seems to be the Sophos version. The newest version I installed (11), they delegated the boundschecking code to a 3rd-party solution called hitmanpro.alert (hmpalert.dll). Looking at reported minidumps, none of the ~10 I looked at included hmpalert.dll.

The version I installed does inject sophos_detoured.dll, but it delegates all the boundschecking work to hmpalert.dll, which appears to behave better.

In order to repro this I'd need an older installer.
Oof, we've had some serious issues with hmpalert in the past: see history in bug 1329994, bug 1300480, bug 1268025, and earlier.
We also had serious problems with Sophos BOPS and Firefox (most noticeably PDF.js).  Recently we had problems with BOPS and Excel.  We're now disabling BOPS.  I would consider this bug invalid.
