Consent-o-matic: automatically rejects cookie banners, even the most annoying ones.

Bitwarden.

I think all of these also have Chrome versions, but still better on FF due to being able to install (or side-load if not listed or not whitelisted for mobile) onto the mobile version. The day I learned how to get non-whitelisted ones to install and install from xpi was game over for bothering with other mobile browsers.

• FastStream for downloading videos from YT and a lot of other sites (I daily use it for grabbing stuff on Twitter)
• Bypass Paywalls Clean for the obvious (this one is to the dev's not github but same kind of site site as it has to be installed via xpi)
• Watch on Odysee for seeing if a YT channel also uploads to Odysee to go watch there if possible and at least give my view there
• SponsorBlock for being able to skip hard-coded ads from the uploads and other sections of YT videos
• DeArrow for being able to view titles for YT videos that are more reflective of content
• Wayback Machine for saving pages to Archive.org along with saving them to my account on there.
• Privacy Possum for more aggressive blocking of tracking (though it does require remembering it is on if a site breaks as it will block things that uBO isn't the cause of the issue)

Multi-account containers. Let's you have 2 different Gmail accounts open at once. Also I try to silo different parts of my life to prevent tracking.

Noscript and tampermonkey too.

Snowflake - help others bypass censors

Port authority - stops port scanning of your local network [and I found out how many fucking assholes do this. My own employer freaking does it >:( ]

In no particular order;

• Unpaywall - for research papers tries to find legal and free copies of them
• Stylus - overwrite style on a per-website basis (I use the Compact Subscriptions style on YouTube, for example)
• uBlacklist - additional to uBlock that deletes some URLs from search results (such as an anti-AI list, or Pinterest from image search)
• Surmount - jumps over paywalled news articles using archive.ph

Adnauseam Silently click-spams ads to drain their bandwidth, with the purpose of making the horrible advertising business unprofitable.

Tab Snooze - allows you to close a tab and have it reappear at a chosen time later

Domain Volume Control / Better Volume Booster - allow you to set default volume per-domain (note that unfortunately, in the 1st one the set volume gets changed when you change the volume through a site's player, and the 2nd one currently causes an issue on Nightly with unpaused videos)

Playback speed - allows you to change the speed of videos/audio on any site, even only by x0.01 at a time (you can also change the buttons that appear when you click on the addon in the toolbar/addons menu to have specific speeds readily available) (note that it doesn't change the pitch of the audio)

• Specifically for YouTube you can also use an addon like Improve YouTube. To configure the feature click on the addon in the toolbar/addons menu > Shortcuts > Playback speed. To change the shortcut so that you hold Ctrl and use the mousewheel (while hovering over the video) click Ctrl and release it before using the mousewheel up or down accordingly (otherwise it acts as a zoom to the settings window)

Media URL Timestamper - automatically inserts the current timestamp of the YouTube/Twitch video you're watching and updates it in the history in case you accidentally close/navigate away from the page or go to a different time in the video

Feedbro - an RSS reader with filtering capabilities

Oooo, PopUpOff

Haven't had to deal with annoying "LeGiTiMaTe iNtErEsT" cookie pop-ups for nearly a year. Honestly forgot they existed until I needed to deactivate it to briefly log back into my reddit account recently (I swear that entire website's UI is just malware at this point).

Their website is also surprisingly gorgeous. I was surprised since most app makers usually don't put much effort into something people are probably only gonna see once, if they even have one at all. It's so well put together.

Firefox multi account containers and temporary containers

Tree style tabs

Makes it simultaneously easier to open a billion pages but also manages them nicely

Redirector - redirect pages to where you want them to go.

• make the youtube subscription feed the first thing you see / convert shorts without needing another addon
• fix stupid machine translated localizations of pages looking at you learn.microsoft.com or reddit does this too now
• overwrite / define custom duckduckgo search !bangs
• remove tracking parameters from urls
• etc...

Example Usage: https://github.com/einaregilsson/Redirector?tab=readme-ov-file#examples

This extension is how I learned to love RegEx.

I love Indie Wiki Buddy, it auto redirects fandom links to the newer official independent wikis for things that have them (minecraft is one example). God I hate fandom so much truly the worst wiki experience.

Maybe this counts as a "worse version of uBlock" but I use AdNauseam, which in addition to blocking all the ads, it registers as clicking them too, which fucks up their tracking and costs them money. I remember seeing somewhere that the ad blocking itself was based on uBlock, but I couldn’t find it on the extention page so i may have imagined it.

Sponsor Block--Skips some YouTube ads.

Language Tool--keeps me from making stupid grammar errors.

Cookie Quick Manager--you can lock cookies and other stuff.

I'll throw out a few.

• LibRedirect

• Chameleon

• NoScript

The one I want to point out the most is WebScrapbook, which is alternative to SingleFile. It can either snapshot the current DOM or the document source (handy for PDFs), can use proper directory structure and provides full-text search over the stored pages.

It has support for separate server should you want to keep the files outside browser storage or share an instance between several browsers. I use this with text browser as renderer to make summarizing pages into VimWiki easier.

Unfortunately it can't do sync between instances, that's something I wanted to add to it but I'm currently juggling way too many other projects.

Then there's Feed Previews for getting those RSS/ATOM feeds where they still exist so I can avoid using the browser, or worse, getting notifications through antisocial media. (-:

Web Archives is making access to webpage archives much more convenient. Especially useful when dredging through old academic research pages full of link rot, or using TOR and getting locked out constantly.

For managing tabs I'm sticking with the venerable Tree Style Tabs together with few handy plugins like TST: Colored Tabs and TST: Unload Tabs.

While I prefer keyboard control for most things, and certainly Tridactyl goes the furthest from existing addons, it just can't really handle all the screens as it was possible with the XPI addons. sheds a tear

For content blocking it's the run of the mill uBlock with JS disabled by default (F8 mapped to selectively enable it on a page) and LocalCDN which has rule generator for whitelisting locally provided resources in uBlock.

And because some sites are broken mess and don't work even with conservative Firefox setup I've had to use Allow CORS once or twice.

Non-addon bonus: Searx-NG has a CSV output which can be integrated with tools like rofi or dmenu so you can do web searches outside web browser and easily pick the result.

I use a bunch of YouTube enhancing extensions.

SponsorBlock. so very, very good. First user into a video after it drops, who has this extension, marks the portion of it that is the YouTuber's ad read / sponsor segment. Extension auto-skips it for every user who watches after. Saves a lot of time.

Multiselect for YouTube. Just what it sounds like, you can select multiple videos at once to add or delete from playlists, instead of doing them one at a time.

PlayerTube. Use approximations of player UIs from bygone years. I'm partial to 2013 myself.

Return YouTube Dislike and YouTube Shorts Block. Self explanatory from titles.

Others (non-YT) I use...

Change Case. I watch my keyboard and not my screen whilst typing, and this just lets me quickly flip large chunks of unnoticed caps-lock text back to normal once I discover it, rather than having to retype it all.

Simple Translate. Quickly run highlighted text through a translator on the right click menu.

• Cookie Autodelete
• I don’t care about cookies

I like to use mouse gestures since the time Opera had its own engine. So basically the Gesturefy add-on for Firefox is a must for me.

The first thing I add after an ad blocker on a fresh Firefox install will always be Shinigami Eyes: a crowd-sourced system for marking transphobes and allies across the web.

Sidebery

On desktop I really like Vimium. It enables keyboard navigation on basically any site

Tridactyl is a must for me. It's as close to the Qutebrowser experience as I can find (especially with ':guiset none') but I get to keep my ublock/sponsorblocks.

nuTensor. Paired with uBO it's easily the best browser firewall system.

Tabs aside.

Nothing you can't do with bookmarks, but it's a much nicer interface.

JShelter?
