Add-Ons not working, Can't download/install new ones
Last night around 10-ish my add-ons quit working suddenly. Now I remember something like this happened last month but I also saw it happened to several people so I wasn't worried. But I didn't see a topic about it this time (although I might not have looked well enough?) so I don't know if it's just me.
It won't let me try to install an alternative add-on, and if I right click it'll say to check my connection, but isn't my connection fine if I'm using the internet anyway? Right clicking it says it's a corruption issue.

The certificate used by the add-ons expired. https://support.mozilla.org/en-US/questions/1258165#answer-1218833 fixed the issue for my v54.

Why are you using this very old Firefox version with known security vulnerabilities?
