umatrix. ..underappreciated imo.
take a shot for everytime sum1 mentions ublock.
get $100 dollars everytime sum1 mentions umatrix.
im still broke but wasted AF!

I don't use many extensions, but apart from the usual UBlock Origin I'll say something exotic: UltraWideo

Because sites like disney+ still don't know that 21:9 monitors exist so you have to force it to scale their 21:9 films to your monitor instead of giving you black bars on all sides

LibRedirect: redirect Website links to alternative frontends like Nitter, invidious, rimgo etc. - couldn't live without it especially on mobile where using Twitter without the app is really obnoxious

CookieAutoDelete combined with 'I still don't care about cookies': delete cookies the moment you close the tab if not whitelisted, also remove cookie notices and accept all cookies.

Nano Gestures: mouse gestures for navigating websites

Mandatory:

• Dark Reader for dark mode anywhere, and Invert Colors for the occasions when a site is not usable with Dark Reader.
• Ublock Origin of course, but I also still use uMatrix because even several years after it stopped being maintained, it's STILL unmatched by any other addon in the content-blocker category. The granularity of being able to specifically allow scripts or frames or images or cookies from specific third-party domains or subdomains either everywhere or only on certain first-party domains, with a very intuitive visual grid (matrix) and subdomain selection, is incredible. I still don't understand why it's deprecated.
• Tree Style Tab and the related Tab Unloader. I forget things exist if they aren't right in front of me, so if I have any intention of coming back to a site or a workflow, I need those tabs somewhere in front of me, tucked away in a tree waiting for me to get back to them. I regularly have between 100-200 tabs open. Being able to unload performance-heavy tabs without restarting the whole browser also helps a lot.
• Bitwarden because if you aren't using some kind of password manager, do you even care about security?
• Translate Web Pages because not everything I want to read is in English

Nice to haves:

• Tranquility Reader, because the browser's built-in Reader View often shits itself and doesn't work, particularly on social media text posts. This lets me select the page contents I want it to grab in case the automated picker fails. It's still a bit janky though; if anyone has a more polished alternative, I'd like to hear about it!
• Enhancer For YouTube, Sponsorblock, and Return YouTube Dislike
• stutter For when I feel like speed-reading
• Toolbox for Google Play Store

I'm on Vivaldi so I don't know how many of these are available to Firefox. Leaving out all the obvious ones like adblocker, password manager, userscripts, etc.

Privacy Pass; do less captchas. Every time you solve a captcha, it stores a few "tokens" in your browser, essentially verifying you as human extra times at once. The next few times you encounter the same brand of catcha, your browser will "spend" one of those tokens to automatically be treated as high confidence, skipping the captcha.

Bot Sentinel; puts a little score next to people's names on Twitter, showing how often they've been reported to the Bot Sentinel site for various things like spam, trolling, or hatespeech; it's nice to know at a glance when you just shouldn't engage with someone.

Jiffy Reader; when it's enabled, hilights the first couple letters of every word, which is great for ADHD because it makes your automatic reflex be to look at each word one at a time, rather than skim the whole section.

Teleparty; watch netflix, etc, with friends, with a little built-in chatroom

Trim; show IMDB/Rotten Tomato ratings on netflix, etc, thumbnails; a real minor tweak, but I'm a big fan

Beyond20 and the VTT Enhancement Suite; specialized D&D addons that made playing online so much easier during the pandemic. Beyond20 pipes your character sheet macro rolls from D&D Beyond directly into Roll20, and VTTES adds all sorts of bonus functionality to Roll20.

Firefox: tridactyl, jumpcutter, sidebery (best tree tabs I can find), temporary containers, cookie remover

Firefox (I am not going to repeat the obvious ones that have been mentioned numerous times):

• IPvFoo: Display IP address information for website
• tabdetach: I always juggle around my windows. Being able to detach, attach and merge tabs without using the mouse is really useful.
• Cookie AutoDelete: Removes cookies unless whitelisted

Chrome:

• Steam DB
• JSON Viewer

Safari:

• PiPifier
• Vinegar
• Sponsorblock
• Eat the shorts (no longer available)

I physically can't use a browser without Vimium anymore.
