Title:
firefox 67 keeps crashing on me
Status in firefox package in Ubuntu:
Incomplete
Bug description:
A system that's been extremely good and stable has all of a sudden
become completely unusable after running Software Update.
After the last update, my system won't load firefox properly half of
the time. After loading pages like youtube it crashes the tab or just
crashes the entire browser. Sometimes it will immediately crash upon
launch and either restart the X server or just freeze.
I really don't know if it's firefox to blame or some kernel update.
My good system has become completely and totally unusable. Terribly
frustrating.
Ubuntu 18.04.2 LTS, firefox 67.0, core i7-2600, AMD Cedar graphics.
