I used enhancer but it seems the dev has stopped updating it for Firefox and only updating it for chrome.

Moved to Tweaks for YouTube and am quite happy with it so far; seems to also have more options.

Love libretube but it just wouldn’t play videos consistently. Ended up moving to grayjay

I don’t think so, I actually updated it via f-droid before but resorted to sideloading the apk myself for faster updates.

I’ve noticed it so far for my apps: Tilla (subscription manager), ChatGPT, Poe

Apk from their gitlab page

For what it’s worth I use aurora store and have already noticed some apps refusing to open/work unless I reinstall them from the play store.
