I was a mad Opera user about 25 years ago, it was the best browser by miles at the time. One feature it had was mouse gestures. Mouse gestures and uBlock origin are the only two extensions I can’t love without, but these lists never mention them so I feel like the only one who uses them.
It’s hard to explain how cool and quick it is to be able to control your browser with the mouse. Open/close tabs, navigate tabs, back/forward etc. It doesn’t sound useful, I’m usually a mad keyboard shortcut fiend. But with web browsing in particular, your hand is already on the mouse, scrolling.
The specific extension I use is Gesturefy, I encourage people to install it and give mouse gestures a go.
LibRedirect - redirects common proprietary sites to a free and open source alternative
Tampermonkey - allows you to find and install custom open source scripts that add functionality to websites
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.
uBO, Facebook container, Bitwarden, Privacy Badger. People say uBO already covers Privacy Badger but I like keeping it there because of the replace widget feature.
Ublock, decentralize, adblockplus, noscript, snowflake. (This is what I used on ff, but I use brave for a while now and its so much easier, brave + invidious)
Related to CDN stuff, there’s LocalCDN, which I believe downloads the most commonly used scripts from various CDNs and hosts them locally, reducing the amount of tracking they can do as they aren’t being pulled from the source each time.
Im using Firefox/a fork of it - please note that many of the below mentioned extensions either only exist for Firefox or don’t work well with Chromium browsers due to manifest V3.
edit: “isn’t this implemented in-browser?” comments: maybe, but it’s to the browser’s implementation. These plugins are reviewable separate from their analogous browser implementation.
Isn’t NoScript redundant if you run UBO in medium mode?
Roughly similar to using Adblock Plus with many filter lists + NoScript with 1st-party scripts/frames automatically trusted. Unlike NoScript however, you can easily point-and-click to block/allow scripts on a per-site basis.
