For me I use the following:
Temporary containers - This add-on is so amazing and really helps when signing into multiple accounts
UBlock Origin - Add blocker, probably the best available
Dark Reader - Helps to make the web a little more readable and less harmful to the eyes
uBO and Strongbox for PW management (used to be 1P, but since they forced everyone away from being able to store your vault locally, they had to go).
