I'm not gonna lie, I'm a little bit of an extensions hoarder, which is bad for fingerprinting ๐ฃ, but I seriously do use the extra ones.
Vital:
uBlock - obviously, some people even suggest to only use this extension and nothing else to reduce fingerprinting. Make sure to enable those filters! Also check out the advanced mode, eliminates the need for NoScript.
Not Vital But Really Good To Have:
LibRedirect - Never worry again about visiting the original social media site, you can immediately be redirected to a proxy version of the site that doesn't stalk you. Great when I'm forced to click a Twitter, Reddit, Youtube, etc. link. Unfortunately, some proxy services are dead (Instagram, Tiktok, Invidious is always under threat, etc.)
Bitwarden - Password manager
Dark Reader - Nice, especially on fingerprint resisting browsers like Librewolf that don't let your browser/sites see your system settings to automatically pick the dark mode of a website. Have singed my eyes a couple times.
For Language Learners (like me):
Yomitan - The GOAT of tools, a popup dictionary that can be used to instantly look up the definition of a word in your target language, and connects with Anki, a flashcard app. I use it for making vocabulary cards from Japanese media I consume. Literally all the other resources are meant to be paired with this.
Asbplayer - Lets you add subtitles to whatever media you're streaming and makes the text selectable. Paired with Yomitan, you can easily make Anki flashcards from the TV/Movies/Videos you watch.
Lap Clipboard Inserter - By using a clipboard extension with Textractor, you can hook a game/visual novel and auto-copy all the game text to a webpage, which can be paired with Yomitan (you guessed it!) to look up words. You have to turn it on for individual pages, so don't worry about it constantly stalking you.
Neat, But Random:
Mastodon Streetpass - Helps you figure out if a person is on Mastodon by looking for a custom link on their site. Collects a list of them and tells you the date that it found the account. Basically just browse as usual and it will passively collect a list.
