This report is not actionable because we need either exact steps how to reproduce the crash or we need a stack trace with debug symbols. You can use a Mozilla.org build and use the integrated crash reporter and send a crash report. see https://developer.mozilla.org/en-US/docs/Mozilla/How_to_get_a_stacktrace_for_a_bug_report

Thanks for your fast answer! This is at least triggered by (simulating) I/O errors, will generate you a trace next week.

need to give it another week. only got Bus Error for lay tries removing the medium and could not reproduce a proper i/o error with fiu so far with: fiu-run ./firefox-60.1.0esr/firefox & export ffpid="$(pidof firefox)" fiu-ctrl -c 'enable name=posix/io/*' $ffpid

I'm looking at bug reports in the File Handling component to determine if an action is needed. It seems that here we're waiting for more information in order to determine if this is an actionable bug. If the information is not available, I'd recommend closing the bug.

Thanks for the reminder! This is still waiting for info (by me or someone else). STR 1. set up a partition with unfriendly fs 2. move firefox there and start it (or with fiu) 3. deny it file access and see it crash after some time So far i was only able to reproduce Bus errors: https://trac.torproject.org/projects/tor/ticket/27110#comment:2

I can confirm this bug, but I can't say an exact step to reproduce, it simply occurs, while watching videos on youtube, while using web.whatsapp, it even occurred while having a freedesktop.org page open while an youtube video was being played. Here is the segfault in dmesg log (Firefox Quantum 60.3.0esr (64-bit) from debian testing): [ 1533.633423] do_general_protection: 9 callbacks suppressed [ 1533.633425] traps: Web Content[1928] general protection ip:7fd9c4f9b41d sp:7fff3ba0fd90 error:0 in libxul.so[7fd9c4f2a000+57e2000] [ 3899.332815] Web Content[2536]: segfault at 800000 ip 00007f63b0c7e6d8 sp 00007ffc61ed6768 error 4 in libxul.so[7f63ad5d8000+57e2000] [ 3899.332824] Code: 00 00 8b 47 0c 83 f8 01 76 20 83 f8 02 74 13 48 83 ef 08 e9 ca b2 00 00 66 2e 0f 1f 84 00 00 00 00 00 f3 c3 66 0f 1f 44 00 00 <48> 8b 36 e9 60 ff ff ff 8b 47 0c 83 f8 01 76 20 83 f8 02 74 13 48 What I can say is that I'm using Ryzen and it's being a complete hell to use it under linux. Even my PCI-Ex gpus are failing because of the problems.

Possibly the same error message for multiple problems on the other links but I see something that may be similar to this. For me with Ryzen (B450 chipset) + NVIDIA (GeForce 390.87) these type of segfault messages occur without any obvious pattern when using Firefox 63.0.1 compiled from source using GCC 8.2.0 - no such problems with the binary from https://archive.mozilla.org/pub/firefox/releases/. (this setup also has independent PCIe and MCE errors in dmesg). After swapping out the graphics card for an AMD one (amdgpu driver) the compiled from source Firefox runs fine without segfaults (none of the other dmesg errors either).

Moving to gfx based on this, though it's unclear if this bug is still current...

Allan, traums,
Can you still reproduce this issue using newer versions?

Hello, I need to test it. But probably not.
Regarding the Ryzen problems, I had a defective chip that had to be replaced by AMD. Also, after the replacement I had to replace the RAM chips (Corsair) since they weren't following JEDEC specifications properly. This note is just for reference, since I mentioned Ryzen at the time.
I'll do further checkings and I'll report here later.

Assuming this is no longer a problem => WFM
