Firefox Multi-Account Containers has to be one of my favorite extensions. Mixing work accounts and personal accounts in the same browser session but in different tabs has made my workflow much more efficient. You can force bind sites to a container so that you don't accidentally use your personal account for anything workplace related.

Definetely libredirect. It redirects YouTube, Twitter, TikTok... requests to privacy friendly frontends.

Dark Reader, because dark mode rocks.

Consent-O-Matic
Automatic handling of GDPR consent forms

DuckDuckGo Privacy Essentials
I mostly use this for the email protection (highly recommended!)

ScrollAnywhere
Drag scrollbar with middlemouse button anywhere on the page.

I shared one on reddit that replaces pictures of spiders with kittens and it was met with a pretty shocking amount of hatred and vitriol brought my way, so nervous to share it here. But still I thought it was nice.

• uBlock Origin
• Dark Reader
• Bypass Paywalls
• Decentraleyes
• Enhancer for YouTube
• Return YouTube Dislike

uBlock Origin
PrivacyBadger
Return YouTube Dislike
SponsorBlock
Translate (Firefox doesnt have website translation as a native feature)

I run Firefox

• AdNauseam (One step further than uBlock Origin, it actively clicks everything that missed my DNS blocks)
• Bitwarden
• Decentraleyes
• Enhance-O-Tron for Plex (For some reason some videos in my library have black bars hard coded into them. I could probably re-encode them to get rid of the bars, but this add-on just hides the bars at a button click. It's only a problem for monitors wider than 16:9)
• Enhancer for Youtube (TM) (Automatically expand the canvas out to the full screen and a bunch of other stuff.)
• Facebook Container (I don't use facebook, but the containers are nice to keep shit separated)
• Keepa - Amazon Price Tracker
• NoScript
• Redirect AMP to HTML
• ShareX ( I have workflows that automatically store stuff into my nextcloud and setup share links)
• SponsorBlock for Youtube - Skip Sponsorships
• Stylus

I had stuff for Reddit... but since I've moved off the platform, that's been nixed. And for those of you using the cookie accepting apps... Why not just block the element with uBlock?

Other than Ublock Origin and Bitwarden, these are some of my favourites :

Temporary Containers is a new favourite of mine. It works just like container tabs, but the difference is that it deletes the history of that tab once it's closed, similar to Incognito/Private instance.

Reddit Comments for Youtube - If a youtube video has been linked to reddit, then it basically gives a small box which lists all the subs the video has been linked to and shows you the comments. If you're logged into reddit, then it will allow you to comment as well.

Keepa for Amazon. Let's you track price history for any product, so you can see if a sale is actually a real sale or not.

Tab Session Manager - Basically lets you save tab sessions.

Enhancer for Youtube and Pockettube Subscription Manager - Gives various youtube enhancements.

Stylus - To style websites. I mainly use it to fix the youtube thumbnail and font size.

• JShelter actively fights fingerprinting.
• NoScript blocks by domain by default.
• uBlock Origin with cookie list to block ads, trackers, and hide cookie banners.
• DarkReader to help the eyes.
• Stylus to fix any CSS not fixed by the rest.

I use Decentraleyes and Privacy Badger on top of uBlock

Other than the good ole ad blocker, sponsorblock is a godsend

• ublock origin
• privacy badger
• decentraleyes
• clear URLs
• facebook container
• https everywhere
• firefox multi-account containers
• dictionary anywhere

So, let's try to compile a list.

• "uBlock" does not need any kind of introduction. Most of the people who answered the thread use it anyway. But it is my favourite!
• "Language tool" to help me spell things properly, lol
• "I don't care about cookies" to get rid of annoying GDPR-compliance banners
• "FoxyProxy" to easily switch between proxies
• "Vimium C" to navigate the web using vi-like shortcuts
• "SponsorBlock". I don't use YouTube as much nowadays but when I do, this add-on helps me skip in-video advertisements and irrelevant moments
• "Search by image"
• "Rikaichamp" is a great add-on for anyone who often needs to look up Japanese words
• "Runet Censorship Bypass" because censorship circumvention is not a crime in my country. Yet.

Honestly, I thought it will be shorter. It makes me appreciate the authors of all these add-ons even more. If it weren't for their efforts, web browsing would be a much less enjoyable experience.

Dark Reader is amazing. Not just a great idea, but incredible execution.

Cookieautodelete is sooo underrated.

Question: Does anyone know what security and privacy extensions are considered redundant in light of recent Firefox improvements in the past few years?

For example, I saw several people recommend Privacy Badger for example. I thought I heard somewhere that was considered not needed now. I do not know for sure so am frankly confused by this and some of the other extensions which I too use to use.

For me I have kind of stopped using most security/privacy extensions except uBlockOrigin and then just configuring Firefox rather tightly. Not sure if this is best approach or not. On one hand every extension increases the attack surface and the uniqueness of the browser so there is a point about less is better, on the other hand some may be useful too.

Thoughts? Thanks.

Tree Style Tabs for Firefox gets installed on every Desktop install I use.

SingleFile ! Best method of keeping pages for offline use !

I'm using FF and I only have one extension, it's ublock origin

I wish you’d recommended that commenters keep to “one extension per top-level comment,” making it easier to upvote the best ones 😅

Anyway, my “one pick” is definitely Tridactyl — a thorough, absurdly powerful poweruser-mode for FireFox based in Vi-like modal interaction.

https://github.com/tridactyl/tridactyl

ublock origin, sponsorblock, return youtube dislike, clearurls and dark reader

Mine's Redirector. I use it to force redirection of some URLs, for example:

• Redirecting an amp URL to a non-amp
• Redirecting the URL of a small-scaled image to the URL of the original size
• Redirecting a mobile site to its desktop equvalent (e.g. Wikipedia)
• When I was using Reddit, I also used this extension to force all links to go to old.reddit.com

One i done see mentioned is OneTab. Allows me to take large groups of tabs and dump them to a text file, which I can also use to restore groups of tabs. It allows me to close entire browsers full of tabs but keep the links to prevent firefox from getting out of hand with ram consumption.

• bitwarden
• simplelogin
• proton vpn

I just use these three.

Firefox: uBlock Origin, Bitwarden, Simple Tab Groups, New Tab Suspender, SponsorBlock for YouTube.

I don't think I can live without Sidebery anymore, it adds a sidebar for managing and easily grouping tabs. Although it's really made my habit of not closing them even worse...

It gets quite extensive for me by now

• uBlock Origin
• Consent-O-Matic
• Dark Reader
• Bitwarden
• Tab Session Manager

• SponsorBlock for Youtube
• Return Youtube Dislike
• Clickbait Remover for Youtube
• Auto HD / 4k / 8k für YouTube

• Alternate Player for Twitch.tv

• Augmented Steam
• Show Great on Deck on Steam
• alike03's Subscription Info on Steam

• Keepa - Amazon Price Tracker

And a few additional ones for selfhosted apps like FreshRSS Checker

• LibRedirect Alternative open source frontends, very useful to survive on sites like Youtube, Twitter, Imgur etc.

• Voat - Reddit Comments on YouTube & Web Pages Not so useful any more, but you can read what Reddit communities have to say about websites

• Snowflake Fight cencorship

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

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

Pushbullet - send stuff from my phone to my browser, or vice versa.

Camelizer - camelcamelcamel popup for Amazon browsing. CCC displays a price/time graph and lets you set alerts for when something is below a target price.

Youtube Playback Speed Control - I watch YT at 2x speed usually, sometimes 4x. This adds fine control and keyboard shortcuts for that.
