It just constantly stops working. Installed it clean, didn't change any settings, imported the updated sieves. When reinstalling, it works for like 20 minutes and then just breaks again. Never had this problem with the original, so sadly going back there for now. Firefox 124.0.2 (64-Bit).
Edit: Tried it again. It also fails to fetch videos and image galleries directly from new.reddit.com - the original Imagus does this without any problems.
I really wish this was fixed, as some features, like the page dimming one, seem very nice to have.
