I'm having a persistent problem with Firefox and my computer. After browsing for a while when I open a new tab and try to load a web page large parts of Firefox become unresponsive, for example I can close other tabs, move tabs, use websites in other Firefox windows largely unaffected but I cannot view other tabs in the window I opened the crashing tab. The unresponsive tab just sits there with a loading animation in the tab name, white screen, what ever website I tried to visit cleared from the address bar. Opening additional tabs is possible but the crashing window will not switch to those tabs, while in another window I can open a new tab but actually visiting a site or opening a link in a new tab will crash that window. Opening new windows once I'm crashing results in a crashed window regardless if I use the empty page or load a URL. Lastly if I click on a link before a tab crashes nothing will happen. No tab will open, no tabs will crash, the link won't turn purple. But at this point I can go fully about my business reading the existing loaded content in all my working tabs and windows. Opening the link in a new tab with context menus will crash the new tab immediately. Once a tab has crashed I am forced to close the browser. It usually takes a while to fully shutdown, but it's never unresponsive enough to need to be killed in the Task Manager. And sometimes this entire process corrupts my profile and I get to re-login to everything on the web again. Now, here's the frustrating part. I don't know how to troubleshoot this. The issue has persisted through: - Firefox versions 67, 68, and 70 - My machine was re-imaged with a new Windows image when I was upgraded to an SSD. The previous image didn't have Firefox preinstalled, the new image did(68). I purged that and installed 70 and the issue continues. - I have disabled hardware acceleration multiple times(because my profile keeps getting reset). - There are no crash logs. - I haven't taken to time to reproduce the error with no extensions but I've A/B tested that I can crash running just uBlock or just Tusk. I'm not running a lot of extensions because the profile keeps getting reset. - Firefox isn't actually crashing, no crash reports are being generated, Windows event log is clean.
