Category "how the hell isn't this included by default" :

• Copy Plain Text: Adds an option in the right click menu to copy the selected text as plain text, without formatting
• Copy Link Text : Adds an option in the right click menu to copy the text of a link
• Markdown Reader: Show formatted markdown. I tried several extensions for this and this is the one I prefer personally. It has an index panel on the left which is sooo useful.

Category "Preserving your mental health online" :

• uBlock Origin: You really need to block those ads
• Consent-O-Matic: Never see a cookie pop-up again in your life (it auto accepts or refuse in your place).
• SponsorBlock: Skips Youtube sponsorships. You can define which ones you want to skip and which you want to watch (paid ads, self promo, etc)
• Return Youtube Dislike: Show the number of dislikes on videos. It's not a real number, it's extrapolated based on how many people with the app have clicked dislike.
• Youtube No Translate: Keeps titles, descriptions and audio tracks in their original language

Category "Usefull" :

• KeePassXC-Browser: To access your password database from your browser
• Whatever fingerprinting protection you can find (Canvas, Fonts, WebGL, etc.. half those I used have been pulled, haven't found a replacement for all of them)

Category "Would be nice if..." :

• A user agent switcher... if you want all websites to block you 😑
• NoScript: Block javascript and create custom rules to allow it only when and where you want. Or the reverse. It was great a few years ago but I've stopped using it because websites require allowing more and more otherwise nothing works and it's hell can we cancel javascript please?
• Dark Reader: Dark mode for all websites. Can make some websites unreadable, but you can turn it off for that website. Makes everything much slower though so I don't use it.
