Since the 91 update, I can't configure any preferences in Firefox. The boxes are there, but I can't check them. The only way I know if they've been checked is to see how Firefox behaves! Surely this is some kind of bug??? Portions of the Settings panel cannot be set: General, Search, Privacy & Security - anything that has a box to be checked or unchecked, I cannot check. I therefore do not know ANY of my settings! Please help! Also, when I pull up the settings page, once I leave the page, I have to pull it back up again - it doesn't stay but reverts back to the new tab page. Most annoying. Surely this cannot be correct!
