When I focus certain website, i.e. actually view the tab they are loaded in (if they loaded in the background) firefox crashes. If I find a url that causes a crash then that url crashes consistently, but I cannot see a connection between the urls. The crash can happen when viewing a pdf with firefox's internal PDF viewer (no web plugins at all), on explosm.net (static images, no video), the jolla shop (embedded video), some sites on the wayback machine. I have tested in a new profile, and attach the console output, and an strace up to the segfault. Reproducible: Always Steps to Reproduce: 1. $ firefox -ProfileManager (create a new profile and start with it) 2. Visit http://shop.jolla.com Actual Results: Firefox segfaults as the page starts rendering Expected Results: No segfault Portage 2.2.18 (python 2.7.9-final-0, default/linux/amd64/13.0, gcc-4.9.2,

Created attachment 398396 [details] strace of run with new profile
Created attachment 398398 [details] console output
Please provide a backtrace as described here: https://wiki.gentoo.org/wiki/Bugzilla_HOWTO (You will need to rebuild firefox with debug information and run it withing gdb.)
You need to run with firefox --safe-mode before you do anything else. It could be nothing more then an extension/plugin causing you all the headaches.
@Andrew: I will recompile and upload debug output tonight.
@Jory: No difference in behaviour in safe mode, I'm adding the strace and console output for the safe mode runs. These were produced by running $ firefox -safe-mode -ProfileManager &> /tmp/console.txt and $ strace firefox -safe-mode -ProfileManager &> /tmp/strace.txt respectively. I created a new profile for the first run (console), and reused that profile for the second run.

If you would please email me the log to mozilla@gentoo.org so I can view it while out of town.

Does this problem persist in newer versions?
Yes :(
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system. Thank You for your support and understanding The Mozilla Team
