Here's a list of those I have installed:
- uBlock Origin https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/
- Consent-O-Matic https://addons.mozilla.org/en-US/firefox/addon/consent-o-matic/
- SponsorBlock https://addons.mozilla.org/en-US/firefox/addon/sponsorblock/
- Youtube-shorts block https://addons.mozilla.org/en-US/firefox/addon/youtube-shorts-block/
- ClearURLs https://addons.mozilla.org/en-US/firefox/addon/clearurls/ (no longer needed since last update afaik)
- Proton Pass https://addons.mozilla.org/en-US/firefox/addon/proton-pass/ (or bitwarden if you use a password manager)
- Bypass Paywalls Clean https://gitlab.com/magnolia1234/bypass-paywalls-firefox-clean
- LibRedirect https://addons.mozilla.org/en-US/firefox/addon/libredirect/
- Firefox Relay https://addons.mozilla.org/en-US/firefox/addon/private-relay/
- SteamDB https://addons.mozilla.org/en-US/firefox/addon/steam-database/
Some that I use:
Dark Mode
I don't like having a light screen.
- Dark Reader. This does a pretty technically-impressive-to-me job of making reasonable dark versions of pages. It's not perfect -- there are a handful of sites that it needs to be toggled off for, makes something hard to read -- but I'm amazed that it does the job it does.
- Blank Dark Tab: Replace the new tab with a blank page matching Firefox's built-in dark mode
Privacy/Anti-Tracking/Ad-blocking
- uBlock Origin. Ad blocker.
- Privacy Badger. Targets cross-site tracking, EFF project.
- Decentraleyes. Targets CDN tracking.
Paywalls
Some paywalls can be bypassed.
Tweaking Frameworks
- Stylus: Doesn't do anything on its own, but permits collections of third-party themes to be applied to websites to fix annoyances.
- Greasemonkey. This doesn't do anything on its own, but it permits people to publish little modifications to be applied to webpages, permits for a lot of little scripts that fix annoyances on websites. There were a number of useful scripts that I used on Reddit.
Misc
- Edit with Emacs. Permits opening the contents of a textarea in an external emacs instance. Nice for things like, say, writing a large lemmy post in Markdown. I vaguely recall that, at least some years back, there was a way to embed a version of vim in Firefox textareas, so if vim's your cup of tea, that might be interesting, if it's still around.
- Instance Assistant for Lemmy and Kbin. A variety of quality-of-life fixes for lemmy and kbin. Lets one open a given lemmy/kbin post on their local instance if they wind up viewing a page on a remote instance.
- Reddit Enhancement Suite. If you still use Reddit, this has an enormous collection of quality-of-life improvements for Reddit.
EDIT: I don't know if this is the embedded vim that I recall, but Firenvim seems to do roughly the same thing, if not.
EDIT2: There's also some "overlay remover" plugin that can bypass a number of obnoxious overlays that I use on my desktop, but I don't have it installed on this machine. I think that it's Behind the Overlay.
Ublock origin
Makes most recipes appear as a modal dialog covering the stupid blogspam that the sites put up.
There's another one that I can't remember the name of on my desktop computer that allows you to block domains from web searches. Like pinterest.
Edit: it's uBlacklist
LibRedirect for me, works well on both desktop and android
There are only *two must have extensions in Firefox:
- uBlock Origin
- Your password manager’s browser extension
Beyond that it’s all optional. Most things I used to use extensions to accomplish are now possible to accomplish using Firefox’s built in settings or using uBlock Origin.
There are a few other extensions I use that I consider useful but optional:
- Dark Reader
- Facebook Container
- Libredirect
uBlock Origin
Add custom URL redirects, e.g. automatically use Piped or Invideous instance instead of YouTube, use Nitter instead of Twitter, remove Google amp
Edit: I just found out about Libredirect from this post - seems like functionally the same thing I'm using Redirector for, but with rules built in.
uBlock Origin.
I really love the built-in container extension (Multi-Account Containers or something like that). Really good if you need to log in to the same site multiple times or if you don't want someone track you across sites.
Surprised no one has mentioned VideoDownloadHelper yet - https://www.downloadhelper.net/
I've used this since I was a kid and it made me really popular in high school lol. Everyone thought I was a hacker or something.
Nobody mentioned Tridactyl yet so... Tridactyl. It's the best vim keybindings extension for Firefox I've tried.
Ublock Origin or AdGuard Containers
Beyond the other obvious choices of DarkReader, uBlock Origin, and Tree Style Tab:
-
Leechblock NG - limit time spent on addictive websites
-
Tab session manager - save tabs in a more flexible way than the default behaviour
-
Augmented Steam - Price history etc on Steam, including third party stores
-
Nobody has mentioned DeArrow - an add-on that removes clickbait youtube titles and thumbnails. works like sponsorblock, by the same dev.
Deadname remover is also nice
KeePassXC-Browser (Or your preferred password manager)
Basic Plugins:
- uBlock Origin
- Dark Reader
- Password Manager Bitwarden or KeePassXC-Browser. If you going to use KeePassXC. You need to download the manager itself.
Youtube
Random Ones
Obviously, uBlock Origin. Others are multi-account containers, facebook container, privacy badger, bitwarden (if you use it as a password manager), and keepa (if you shop on amazon).
Ublock origin Ghostery Containers (so darn useful) Tampermonkey if you know JavaScript, little tweaks can make some sites much more usable
Custom Context search (forgot the actual name of it and I'm on mobile now). It allows you to add custom searches to your right click, so if you select text and right click, you can search for it on any site with search functionality.
Foxy Gestures
Might not be a useful plugin, but fans of Terry Pratchett might like the GNU Terry Pratchett idea. For librewolf I use this slightly updated add-on which fixes some minor issues (source available).
Flagfox, not that useful but it's interesting to see
Other than ublock:
- Vimium to let you scroll and navigate with your keyboard.
- Your password manager of choice.
You really don't need anything besides uBlock Origin. With that said:
- Your password manager's extension would be convenient.
- LibRedirect is great so that any social links get redirected to privacy-respecting frontends.
- Dark Reader to save your eyes.
About some other ones that are mentioned:
- ClearURLs is not necessary if you configure uBlock Origin to remove the tracking parameters.
- Bypass Paywalls Clean is not necessary if you configure uBlock Origin to replicate this functionality.
Other:
- Firefox Multi-Account Contains is good for managing accounts.
- Temporary Containers is also good for isolating tabs.
IIRC, Privacy Badger and Decentraleyes are no longer necessary with uBlock Origin. Neither is HTTPS Everywhere.
On desktop,
-
uBO, of course
-
Bitwarden (replace with your own password manager)
-
Redirect AMP to HTML
-
Redirector
-
Multi-Account Containers
With these five, you have control over the entire Internet. You can bend it to your will. On mobile, just 1, 3, and 4 (assuming you have your password manager installed at the system level, and until Containers works on mobile).
I also really like Notes for Firefox and Dark Reader, but they're not what I'd call must-have.
-
tab scroller. So you can right-click + scroll to change tabs.
