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
Probably my yahoo mail account. I've mostly transitioned off it, but a few things still come to it and it predates even my gmail account (which I barely ever use either). Apple ID's Hide My Email ability has basically rendered all the other ones pointless though since I can just generate a new fake email address whenever I want to register for something fishy. I wish phone numbers worked the same way.
