LibRedirect. Excellent one, that.

Ublock Origin Privacy badger Cookie AutoDelete

Vimium C

Kill Sticky is a really good one, makes even the most bloated websites readable.

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 Origin
• Reddit Enhancement Suite
• 2FAS Extension
• BitWarden

Ublock Origin, dark reader, bitwarden and user agent switcher if websites are throwing a fit about firefox.

I really only run 3 addons in Firefox currently. Chrome is the same but without UBlock.

• UBlock Origin
• BitWarden
• Streetpass for Mastodon

I try to use a minimum for performance reasons. My big three are uBlock Origin, Dark Reader and a password manager.

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.

I haven't seen these mentioned but they are kinda niche though. I use them for work more than personal usecase but maybe someone else finds them useful.
