uBlock Origin

NoScript

...and then uBlock Origin 5 more times.

• ublock Origin
• NoScript
• Tree Style Tab
• Privacy Badger
• HTTPS Everywhere
• Plasma Integration

-Ublock origin (first place, nonnegotiable)

-Dark reader

• Bypass paywall clean d
• unlock origin

Never needed any other, although i have a few anyways

As with everyone else, I agree that Ublock origin is the first wonder of the world.

Also up there however is just password managers in general, be that bitwarden, lastpass, protonpass, etc...

• uBlock Origin. full stop
• leechblock for (attempting) to stay focused
• Zotero is also pretty nifty if you have a lot of sources/ writing a paper, but I'm not sure it would be one of the seven best

• uBlock Origin
• SponsorBlock
• Consent-O-Matic

I'll add ViolentMonkey (run arbitrary custom script on a site), and Stylus (add custom CSS to a site). These are great for adding extra features/utilities to a site you use a lot, adding dark mode to a website that doesn't support it, etc.

RemovePaywall deserves at least 3rd place

no script, authenticator, bitwarden, power tabs, tab session manager, print friendly, terms of service didn't read.

uBlock Origin, duh.

Privacy Badger.

Mouse Gestures (any of them, there's multiple).

Reader view, because sometimes all you need is the text, in a pleasantly readable format.

Enhancer for Youtube (to force a stable quality level)

Since you already have the 3 most important ones listed, I'll throw a vote for Enhancer for Youtube. Makes Youtube less annoying.
