Crash Data
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170608175746 Steps to reproduce: I have been getting "Gah. Your tab just crashed" for a month (I guess). It worked just fine before. I use linux (openSUSE and Manjaro), and I get this error on both distros. I have tried the portable linux version from Mozilla website. I disabled the HWA, I tried the tips from the support pages. I tried the safe mode. Below are the links to my crash reports: https://crash-stats.mozilla.com/report/index/900902ea-77fd-401b-b8eb-55d2b0170626 https://crash-stats.mozilla.com/report/index/a2607899-5de9-4fb9-b050-e463e0170626 https://crash-stats.mozilla.com/report/index/cdeb48c2-1802-43f9-909b-35bfd0170626 Here it is Graphics section from about:support: https://pastebin.mozilla.org/9025854 Please note that I have no extensions installed. The pages are almost loaded and then I see the crash. Not all websites give a crash, sometimes the crash appears just by closing a tab or switching to another tab. Actual results: Like the Firefox build of the distro, the build from Mozilla website showed the same crash. By disabling the hardware acceleration, I got no positive results. The tips from the support pages did not help. In safe mode the crashes disappeared. However, there was a huge lag. Expected results: I was excepting that by disabling the HWA everything should work, taking into consideration there are no extensions installed. Safe mode disables the HWA and extensions, correct?

All the crashes seem to come from WebGL code. Does disabling WebGL prevent the crashes?

I guess it'd be nice to know the pages you open when the browser crashes, to see if someone can repro, or it rings any bell to anyone.

I tested 2 sites, fiverr.com and upwork.com, and I get crashes with WebGL enabled. I remember having popup messages on fiverr.com saying something about WebGL (1-2 years ago), but the new updates fixed the problem. As I said, sometimes it crashes just by closing a tab, switching to another tab, or open a new tab. If one of 5 tabs crashes, the other 4 crash as well.
Why is HTMLCanvasElementBinding::toDataURL getting called on closing or switching tabs? And why are we getting into the WebGLContext::GetInputStream call?

(In reply to Milan Sreckovic [:milan] from comment #6) > Why is HTMLCanvasElementBinding::toDataURL getting called on closing or > switching tabs? And why are we getting into the > WebGLContext::GetInputStream call? The first question is the answer to the second at least. HTMLCanvasElementBinding::toDataURL requires the canvas data encoded as an image with the given format. It uses ImageEncoder to do this; WebGLContext implements nsICanvasRenderingContextInternal, and for objects of that type, ImageEncoder will just delegate to nsICanvasRenderingContextInternal::GetInputStream to do the encoding. (It would eventually reach back into ImageEncoder::GetInputStream to do the actual encoding of the raw data buffer.) Looks like something in JS is listening to the OfflineAudioCompletionEvent dispatched for an AudioContext (mozilla::dom::OfflineDestinationNodeEngine::OnCompleteTask::Run in the stack trace). From there it does the toDataURL call. It may be doing this continuously but it only fails sometimes?

Jeff suggested that there is a better alternative to WebGLContext::GetInputStream in this case; if that's the case, let's open a bug for making that change. For the second part; there may be a legitimate reason for this, but it sounds like it's the page that's doing something "special", so perhaps there is also a tech evangelism issue here?
