> two tabs open no plugins and it crashes on a machine with 16Gb of ram if left open over night, and the bug is trivial to reproduce Keep in mind that whatever the bug is, it's probably only trivial to reproduce for you. If it truly was globally easy to reproduce, it would send the crash stats (https://crash-stats.mozilla.com/products/Firefox https://crash-stats.mozilla.com/products/Firefox) through the roof. Having said that, it's not good when crashes make your Firefox installation unusable. Firefox has a feature called about:crashes that will provide you with the URLs of your crash reports. Have you considered going to http://support.mozilla.org http://support.mozilla.org and reporting this?
