It worked fine earlier. I come on and no adblock plus and no theme I go to the add on thing and it is listed under unsupported. I try reinstalling adblock and it says it won't because it is corrupt. And I try choosing a different theme and nothing changes.

I have the latest update in firefox (66.0.3 (64-bit)and the theme and adblock plus work just fine in chrome.

This is a problem with an expired intermediate certificate that is used to verify signed extensions that causes extensions to get disabled. This is being worked on.

At about 6:10 PST we received a report that a certificate issue for Firefox is causing add-ons to stop working and add-on installs to fail.
Our team is actively working on a fix. We will update as soon as we have more information.
