Looks like Mozilla is having trouble with folks seeing their extensions running on Firefox just being disabled saying they could not be verified. New versions could not be downloaded with Mozilla's site saying downloading failed etc.. Appears to be spreading. https://www.reddit.com/r/firefox/comments/bkfg00/also_had_all_my_addons_disabled_and_cant/ Had this happen on my Mac version. Ugh, the horror without extensions. Using Vivaldi in the mean time where my extensions work.
