Here are what I use in Firefox:
uBlock Origin (with bells and whistles that is with any and all hosts and filter files I can come by)
NoScript
Multi-account-containers
Using ublock, umatrix, binne-i be gone ,fixed zoom
And firefox runs under apparmor and firejail.
And i used this wiki: https://wiki.kairaven.de/open/app/firefox
(sorry, it’s german)
With the exception of uBlock, you don’t need any of the extensions you mentioned. These are rather questionable. WOT is easy to manipulate and the antivirus stuff has nothing to do under Linux anyway except to transmit your surfing behavior to the manufacturer.
Like @pycrk said the biggest risk is the user in front of the screen.
