ublock origin with the annoyance list activated.

dark reader. It’s not perfect but I get most sites in a usable dark mode.

That’s mostly it.

Ublock Origin

NoScript

Dark Reader

Sponsorblock

Bitwarden

everything else is down to preference.

Bypass Paywalls Clean is fantastic, need to install from xpi though

Firefox Multi-Account Containers

Something not so far mentioned is Tree Style Tab.

If you habitually have a lot of tabs open, you'll probably know how annoying it is finding things when each page title has been condensed down to 4-5 characters. On widescreen displays (especially 16:9), vertical pixels are also a lot more precious, while horizontal ones are plentiful.

For me (3840×2160 display, 200% scale), its vertical tab sidebar fits about 30 tabs before needing a scrollbar, and you get a full width title for each and every one.

It can be a bit of an adjustment at first, but I've been using this since the pre-WebExtensions days (since around Firefox 4.0), it's definitely one of my must-haves.

First of all, install Betterfox, it is not an extension per se, but a set of custom settings. Betterfox offers a lot of fixes, including removed Mozilla telemetry, increased speed, smooth scrolling, privacy protections, etc.

I believe, Betterfox can also be used on Floorp (In case their website doesn't work, here's a Github link - https://github.com/Floorp-Projects), which is a Firefox-based browser with Vivaldi/Opera-like interface. Sounds neat, but i didn't really test it yet.

In case you feel too lazy to install Betterfox/Arkenfox/other user.js modifications, you can use Librewolf instead. It is a version of Firefox with bundled Arkenfox and uBlock Origin.

uMatrix, uBlock Origin, and a mixture of add-ons from Dig Deeper's list are a must for privacy. Also, i recommend reading his other blogposts about software, too. Especially this one

If configuring Redirector is too confusing for you, you can use LibRedirect, it can automatically redirect YouTube to Invidious and Piped, Fandom to Breezewiki, Google to SearX, Twitter to Nitter, and so on, so you won't have to bother with popups and ads.

For password managers, use Bitwarden, if you want to have your passwords synced in the cloud, or KeepassXC, if you want to store them locally.

Block The Rich is a fun little extension for those who are tired of reading billionaire spam, but i did not test it.

Instance Assistant Is made to improve Lemmy and Kbin experience, but, once again, i did not test it.

Also, do not use Google, Bing, Yandex or Brave as your search engine, instead switch to DuckDuckGo, Mojeek, and 4Get or SearX

Ublock Origin & Sponsorblock - for blocking ads

DarkReader - for making all websites "dark mode"

uBlock Origin/Dark Reader/Sponsorblock/KeepassXC

Ublock Origin
Enhanced Steam
TWP - Translate Wep Pages (works better than the native chrome version)
ytc filter (Youtube live chat filter. When general chat becomes spammy)
Tabliss (Better version of the chrome start page)

Dark Reader (How could I forget that...)
Bitwarden (or password manager of your choice)

Ublock origin, bitwarden, dark background and light text, tridactyl

Can I plug my own extension that helps you learn languages by translating random words in sites you read?

• DeArrow - Crowdsource better YouTube titles and thumbnails, technically paid (1$), but you can request free access if you can't/don't want to pay
• Firefox Color - Basic theming
• LibRedirect - Redirect popular websites to privacy-respecting frontends (e.g. YouTube to Invidious, Twitter to Nitter, etc.)
• PronounDB - Add pronoun support to Twitter, Twitch, Github, and Discord.
• Return YouTube Dislike - The name says pretty much everything.
• Shinigami Eyes - Mark transphobic or trans-friendly accounts as such for others with the extension to see
• SponsorBlock for YouTube - Crowdsource sponsored segments in YouTube videos so you know what to skip past
• uBlock Origin - AdBlock, update the block lists regularly if you want to use it with YouTube
• User-Agent Switcher and Manager - Change what browser and OS websites think you're using
• Vencord Web - Browser extension for the Discord client-mod Vencord, doesn't work rn because Discord is redoing some stuff

Honestly the less you can live with the better. For me essentials are always ublock for ads, imagus for better image viewing while browsing and simple translate because I deal with a lot of languages. Also containers is useful for work.

As well as those others have already mentioned, I use:

Linguist is a translation extension that respects your privacy. If you switch to the Bergamot translator it acts in offline mode.

Redirector which allows you to set custom rules so you can redirect (for example) Twitter to Nitter, Instagram to PikUki and also rules to redirect pages that are behind paywalls via 12ft.io (or 1ft.io as 12ft is currently down) .

TamperMonkey a userscript manager. I don't have loads of userscripts but I do have things like SocialFixer for making FB a bit better, Absolute Enable Right Click and Bandcamp Volume Bar.

Consent O matic. Automatically refuse cookie consent

Containers. Makes it very easy to manage multiple accounts for the same sites, like YT, email...

Ublock origin fast-forward and dark reader

My list:

• AdNauseam
• Bitwarden
• Don't fuck with paste
• Ecosia
• Fakespot
• Firefox Multi-Account Containers
• Greasemonkey
• Redirect AMP to HTML
• TrackMeNot
• User-Agent Switcher and Manager
• Wayback Machine

And now I have a special profile just for Youtube so I can run uBlock Origin to shut Google up about my adblocker.

Edit: Also, if you like dark themes, check out Dracula.

People have already mentioned the more popular ones

Apart from those, Id recommend Behind the Overlay- it's an extension that removes a lot of unclosable popups on pages in a single click. Things like "disable your adblock" messages or websites that poorly gatekeep content behind a subscription.

ublock origin, noscript

Lemmy Instance Assistant It does things like if someone links a post and the link takes you to the post on another instance, it adds a button to show the post on your home instance. You can also right click on a page (say, an article on a news site) or image and choose the option to share it on lemmy, which creates a new post. It also has stuff to help you when you click a link to a community but the community is not federated to your server, or you can go to the list of communities on another instance and it will have links to take you to that community on your home instance. That sort of thing. Basically the beginnings of a RES for lemmy.

I also like Dictionary Anywhere, which lets you double click on a word to get a definition, a bit like the one Google one for Chrome.

There are also various container extensions such as a Facebook or Google one, that isolates those sites to attempt to prevent that activity being associated with your activity on other sites. It can be a little annoying to get used to but I use them. The annoying thing is that when you click say a google site from a search result on duckduckgo, it closes the duckduckgo tab and opens the site in a google container, but then you can't click back to go back to the search results.

The general container tabs extension is good too. It keeps separate cookies per container. So say if you have 3 different microsoft accounts, you can create different containers. Then you can open a new tab in a specific container and it will remember the account you logged into last time in that specific container, but doesn't affect other containers or tabs not in a container.

I think the arkenfox project website has some good info on this. For a good privacy baseline, you basically only need to enable strict mode and download the ublock origin extension, then change some settings for the extension (e.g. add filter lists).

https://github.com/arkenfox/user.js/wiki/4.1-Extensions

If, like me, you do a lot of Chromecasting from your browser, you'll want to install fx_cast. You need to do a bit of manual installation to get it running, but it works great when you do.

SimpleTabGroups - organize your tabs
uBlock Origin - adblocker
Prvacy Badger - block trackers
I still don't care about cookies - remove cookie prompts
Stylus - lets you create your own css based on url
Canvss Blocker - prevents finger printing but can break websites.

I still don't care about cookies is a must have, it is so nice to never have to click those prompts again.

A password manager is also nice. I recommend keepassxc and it's addon

A bit offtopic here, but how can I auto hide cookie prompts in uBlock? What I do is that I manually hide them with cosmetic filter, then I never have to worry about accepting them or not (kinda like I still don't care about cookies extension)

Firefox is quite good natively. All I have is ublock and bitwarden

Ogtand sponsorblock. I already pay for YouTube premium so I don't really care about in video ads

Ublock
Imagus mod
Return Youtube Dislike
SponsorBlock for Youtube
Video Download Helper
Zoom Page WE

ublock was already mentioned couple of times. Additionally this one: https://addons.mozilla.org/en-US/firefox/addon/cookie-autodelete/

I still don't care about cookies
