Hi, sorry I'm not tech-savvy at all, wanted to ask the question on discord but it says the invite-link no longer works...

A few weeks ago some YouTube browser extensions stopped working, both at the same time. SponsorBlock and Return Dislikes. ‘Enhancer for Youtube’ works though.

I tried to reinstall the extensions but it didn’t help.
I didn’t install any new extensions for the past years. I have only Ublock, translators, privacy badger, decentraleyes extensions.

I really don’t want to reinstall the browser itself (Firefox, win10), because I will have to manually restore all of my data. I know there’s a sync option but the last time I tried it, it doesn’t sync everything, I had to spend hours manually restoring a lot of the stuff, so I hate to reinstall this browser.
Is there anything else I can try to do? What can even be the reason of these two extensions’ failure?
