User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0 Build ID: 20150806191835 Steps to reproduce: This bug happens on all websites, but more complicated ones seem to trigger it more often. Facebook is a notable source of problems. Actual results: Firefox version 39.0.3 64-bit Ubuntu 15.04, Processor: AMD Phenom(tm) II X6 1090T Processor × 6, Graphics: Gallium 0.4 on AMD PITCAIRN Firefox crashes frequently (usually every 5-10 minutes, but it varies a lot: sometimes every minute, sometimes only once an hour). This doesn't seem limited to Firefox (though Firefox may be triggering it in unique ways); every browser I've tried so far has crashed eventually: Chrome, Qupzilla, and the Ubuntu web browser from the webbrowser-app package. This bug has existed since I installed Ubuntu. Alternative graphics drivers have no effect. I've tried the fglrx package and AMD's fglrx beta drivers, both with and without updates. I have also tried 32-bit versions to no effect. Problem does not occur running Windows on the same computer. Sorry if I haven't filled this out correctly, it's my first time filing a bug report. This has been a serious pain.

Thanks for getting through bugzilla and reporting this issue! Please comment with the crash report URL: https://developer.mozilla.org/en-US/docs/How_to_get_a_stacktrace_for_a_bug_report#How_to_get_a_crash_ID_with_the_Mozilla_Crash_Reporter - the file you attached is not a full crash report. Why do you say the crashes are driver-related?

>> Why do you say the crashes are driver-related? > The report lists "OpenGL: X.Org -- Gallium 0.4 on AMD PITCAIRN -- 3.0 Mesa 10.5.2 -- texture_from_pixmap" > which looks like a graphics driver issue. No idea why though I believe we just unconditionally add some information about the graphics on your system to each crash report (to help troubleshooting the crashes that *are* driver-related): http://hg.mozilla.org/mozilla-central/annotate/2ddfc9180971/widget/GfxInfoX11.cpp#l189 The crashes you listed do not seem to implicate graphics in any way. Of the 5 crashes you posted, * 3 are from a nightly build: ** bp-9ccd4cf6-58eb-4d9d-831e-987f32150815 [@ void DoMarking<T>(js::GCMarker*, js::jit::JitCode*) ] in GC ** bp-f911650a-a92a-4adc-b8da-6eb462150815 [@ libuuid.so.1.3.0@0x8957c ] inside EnterBaseline ** bp-e7bc30a6-4866-43bb-916a-d4a9a2150815 [@ EnterBaseline ] (content process) * 2 are from v40.0: ** bp-ef7a6176-7d3b-4a9f-b353-299122150815 [@ js::num_toString ] (failed to unwind the stack) ** bp-05338802-c275-4fde-9c0b-e0c102150814 [@ EnterBaseline ] Unfortunately, as far as I can see, none of the crash reports point to the source of the problem. EnterBaseline, in particular, is the generic signature for crashes inside the JIT-compiled code (cf. bug 858032), and GC crashes are usually caused by the problems not captured in the stack trace. I see from the crash reports that you don't have extensions installed, but just to make sure -- does the problem reproduce in a new profile <https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles> with all the plugins disabled? Also, since you mention general instability, I would guess there might be a problem with HW (but you say Windows on the same computer runs fine...) or with the system (can you reproduce with a stock install of Ubuntu? Do you run it via dual-booting or inside a VM?)

Firefox on Windows does crash but far less frequently, maybe once every few days. Sorry for being misleading about that. Those crash reports are from a nightly build because I downloaded a nightly build so it would have debug symbols. I will reproduce the bug on whatever version/build you like, just post a link. It doesn't seem to make a difference from a user perspective what version I run, they're all equally affected. I dual boot Windows and Linux. I tested it on a clean Ubuntu install and on a live USB—the bug still behaved exactly the same. Crash reports from live USB (nightly build): bp-06d8d9f1-9345-4dff-b27f-c0e872150822 bp-b4ea764e-bebc-43b9-b2ec-dfc8b2150822 bp-084d60c6-f889-4b75-ad1b-f4e5b2150822 bp-0f018f89-b434-4b53-89d5-4f1f32150822 Crash reports from a clean Ubuntu install: bp-3011b737-95f0-473a-bc70-ae2472150821 bp-a9b9b994-7dd2-43ec-8451-705052150821 bp-ef8eb8e9-0fe5-418d-b723-9f0e62150821 Crash reports from Windows (these don't have symbols because they're old. I'm running a nightly build as my default browser now but it doesn't crash very often, I will post a crash report if it does. Sorry if they aren't very helpful. At the very least it's a demonstration that it isn't just Linux): bp-c24a241d-77a5-4329-844b-9c1cd2150820 bp-690fb270-b198-4fdd-8b2a-812402150815 bp-79ed57d6-74ea-4284-b485-e51632150815 bp-528d9344-a904-42f7-9a80-2db6c2150813 bp-c68805f8-f487-473b-8d47-0c82d2150812 bp-97a0aca0-1ecd-4079-8dba-6f79b2150812 bp-45298e0f-9b93-432d-af00-6463e2150810 bp-34440460-374a-4f74-be56-caadf2150809 bp-e3414aa7-9867-4c4a-b8d2-63db82150809 bp-53c8434a-8b91-4813-87d9-03a562150808 Thanks for your attention!

Sorry, I'm out of ideas. Perhaps someone else will see something I don't, but to me this does look like a system-level (hardware?) problem. I'd start by running hardware-level diagnostics (memtest and so on), but I haven't done that in a long time, so I won't be able to help with more specific suggestions.

Oh well, thanks for your time all the same! I ran memtest last week and all results were normal but I'll see if I can find some other hardware tests.

¡Hola Thomas! Is this still a problem? If so, do you happen to have more precise steps to reproduce the crash now? Else, please mark this RESOLVED WORKSFORME in Status at the bottom of ¡Gracias! Alex
