My Firefix Quantum (59.0.2) is a nightmare - after even just a few minutes after start-up, slow, laggy for typing & switching between browsers, and grinds to a halt so I have to re-not start - which is frustrating and becoming unworkable.
I had this problem previously and managed to fix it with an "about:config" solution, but unfortunately I don't remember what.
That said, I since experienced a lot of problems with "Stop Code Kernel Security Check Failure" Blue Screen of Death, despite drivers updated, which ended up corrupting my old Firefox profile so it wouldn't start up.
I had to create a new profile to fix that, but so am since back to this slow and laggy issue again, despite trying many of the "about:config" solutions suggested here (including 'accessibility.force_disabled' change to value 1), nothing seems to work.
Btw, when I open Task manager, Firefox shows 7 'sub' icons despite having 2 windows open and many more tabs for each - 'Memory' for that is running at 670MB - 78% in total, 12% CPU.
Any suggestions? Thank you!
