Burned By An Update To 86.0!
Just updated after a long time from 66.0.5 -> 72.0.2 -> 86.0. This is what FF wanted to do for some unexplained reason so I just let it.
Now when I open a new tab in an open window I get a white screen and nothing works. Entering a URL in the bar or pressing any of the buttons like home does nothing whatsoever. Just a blank white screen.
This is why I LOATHE updating anything! The odds of breaking something that was working perfectly is VERY high. Proved the point once again. I used to let FF update itself and then got burned by the Quantum update that trashed ALL of my open session windows. Turned auto-update OFF after that so that could manually grab and save a copy of the profile BEFORE any update happens.
So how do I fix this or is it a legitimate BUG that should be reported (and how to do same)?
