Outside of what has already been mentioned, I still don’t care about cookies and cookie autodelete in tandem. The first accepts cookies. The second deletes them when you are done.
These are a bit unique from the lists everyone else has, I think:
Lemmy Keyboard Navigation (like the kbd shortcuts from RES)
Google Popup Blocker (stop the annoying log in with Google popups everywhere on the web)
OneTab (this one lets you collapse a whole window of tabs down into a list in the OneTab tab that you can later reexpand into a window again when you re-attack whatever subject all the tabs were about)
These are the more standard ones that everyone seems to run:
Ublock, decentralize, adblockplus, noscript, snowflake. (This is what I used on ff, but I use brave for a while now and its so much easier, brave + invidious)
uBO, Facebook container, Bitwarden, Privacy Badger. People say uBO already covers Privacy Badger but I like keeping it there because of the replace widget feature.
