Despite trying at various points throughout the day, I've not been able to make it crash at all. I've been using it on Trusty/x86-64 for the last hour and a half or so and it's not crashed once.
There must be something I'm missing here. Have you installed any third party software at all? We had a problem a couple of weeks ago where people were reporting Firefox not starting, and it turned out to be caused by a dodgy Sophos AV update. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1474003 Title: Firefox 39 keeps crashing Status in firefox package in Ubuntu: Confirmed Bug description: Firefox 39 keeps crashing after update from Firefox 38. Crashes are random but when idle happens at least once a hour or more frequently when actively used. When replaced with binaries from Mozilla there is no problems at same machine with same profile.
