Firefox 43 segfaulting

mkaito · 2015-12-24 14:07:56

Recently, Firefox started segfaulting:

❯ firefox -p
[1]    11808 segmentation fault (core dumped)  firefox -p

And that's all she wrote. I got a coredump from coredumpctl and ran firefox under strace, but can't seem to make much sense of it.

Core dump

Strace output

A couple people here have had issues with their profiles after the recent upgrade of FF. Perhaps if you tried with a clean profile be deleting or moving your old one?

mkaito · 2015-12-24 18:01:05

Yep. I deleted the profile. It does not appear to change anything about the segfault.

This is the first version to come with GTK3, right? I've made sure Adwaita is installed and no custom theme is defined, so it should in theory use that. Doesn't really seem to change anything about the segfault either, though.

It's probably an extension that is having problems with GTK3. I run Firefox with two profiles. One profile is having around 80 extensions and segfaults, the other one has around 20 extensions and no problems at all, but i can't bother to troubleshoot.

mkaito · 2015-12-25 14:15:12

There should be no extensions at all after erasing the profile.

Not sure if it's related but Firefox starteg segfaulting for me as well. Every time I open a youtube video it crashes after a second.

Oops, sory i didn't pay atention to your previous post. Anyways, I'm using KDE and after i changed the GTK3 theme to 'default' in kde system settings the segfaults stopped.

mkaito · 2015-12-26 02:06:06

Changing the GTK{2,3} theme doesn't seem to do anything about the segfault.

Firefox started to segfault for me as well. Running Firefox under gdb I get:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffd00ff700 (LWP 4703)]
0x00007fffbfd9f140 in ?? () from /usr/lib/xorg/modules/dri/i965_dri.so

If I downgrade mesa to 11.0.7 it doesn't segfault anymore.

I've had this as well. I could only fix this by setting layers.acceleration.disabled to true or by forcing Flash.

I had layers.acceleration.force-enabled set to true, changing it to false solved the issue for me.

Bump.

Still crashing. Still can't figure out why it does that. Asked in #archlinux, nobody was able to help me.

pig · 2016-03-09 16:23:29

I'm in the same situation.

mkaito · 2016-03-09 16:38:32

I installed

firefox-gtk2-bin

from AUR and things work again. GTK3 breaks everything it touches, I swear.

I haven't tagged the thread as solved because I still don't know why GTK3 breaks firefox. Switching themes diidn't seem to help.

sokuban · 2016-04-10 12:00:40

I have been in the same situation since probably around the same time as you. Been self-compiling an old version of firefox at every gtk update since I couldn't figure out any other way to get things to work, but I was too busy to do it after the last gtk update and needed firefox fast to be able to do work.

Thanks so much for suggesting using gtk2-bin, this works and has saved me from lots of trouble. I don't have the free time to compile firefox or troubleshoot this error. I never would have considered using gtk2 because I thought it was a problem with firefox version 43 and up. I'm glad I can get 45 working on my computer now without having to resort to self-compiling.

Hopefully we can figure out what broke it on gtk3 soon, but to be honest, I'd probably just be happy to use the gtk2-bin forever.

EDIT: Well, looks like we're going to be in trouble if that maintainer takes firefox-gtk2-bin off the AUR. What should we do?

I had similar issues, I couldn't move tabs while using the Tabkit addon, or even change the default program to open PDF files. firefox-gtk2 solved it for now, and it feels quite faster as well.

sokuban · 2016-09-20 05:41:17

I just realized firefox-gtk2-bin indeed was taken off the AUR. I compiled firefox-gtk2 by myself and that works fine, but firefox is not fun to compile. The normal firefox in the repos still doesn't work for me. Anyone else with the problem found any solutions?

henk · 2016-09-20 12:00:39

The firefox-gtk2 version is available on archlinuxcn.
You can add the repository to your pacman.conf, but mind you,it is an unofficial one. On the other hand, I'm using it for a few months now
without problems......

sokuban · 2016-09-22 08:00:12

Thanks for the suggestion.

Yea, I guess it would be really nice if we could figure out you know, why firefox gtk3 segfaults for us and how to solve it, but oh well.

WorMzy · 2016-09-22 11:29:44

As there has been no new information in over nine months, and the OP hasn't been on the forums since March, I'm going to go ahead and close this old topic to prevent further zombification.
