Hi plew29881
I would recommend taking a backup of your profile first (do this with Firefox completely closed) and then update following this guide - https://support.mozilla.org/en-US/kb/update-firefox-latest-release. If you need a hand with this, please ask and we will do our best to help.
can this upcoming disastrous certificate armageddon disabling all addons caused by mozilla be circumvented by simply turning back system time to a "supported" year like 2024 while using firefox 56 and ff90 on mint?

To ahonx.n21: No answer to your post will be found here. Have you tried Reddit's Firefox groups? May find technical solution and like-minded users there. This page is a dead end for you.
ahonx.n21, can you please stop post bumping this thread like a stuck record player.
