Firefox

• ublock origin (not just ublock)
• bitwarden as password manager
• Bypass Paywalls https://gitlab.com/magnolia1234/bypass-paywalls-firefox-clean

Some extensions used by me:

• uBlock Origin
• Firefox Translations (works on-device)
• LibRedirect (redirects from certain sites (like youtube) to their frontends (like invidious))

For android I also use Android PDF.js, to view pdf files on mobile.

Dark reader is a good one. It alters websites so they're dark mode, even if they don't officially support.

uBlock Origin is a must for ad blocking. Anything else is just extra flavour. I like SponserBlock and Return YT Dislikes.

uBlock Origin is just required for me to block ads and other annoyances. Generally I also use it to block the annoying cookie popups instead of clicking any of their buttons instead of opting for a different extension, like I don't care about cookies.

I also almost always have Tree-Style Tab, though I've found that it can cause Firefox to be non-performant on memory-constrained devices. This extension gives you a tab sidebar (using a similar interface element like the bookmarks sidebar) that organizes your tabs in a tree. I will often have hundreds of tabs open normally, and this makes them more manageable, as I middle-click everything to open things in a new tab, particularly when I'm researching. It gives a nice rudimentary tree view of what content related to what, like if I'm on a Wikipedia dive or TV Tropes dive.

I also usually have Tampermonkey, as I usually want to make a website more accessible. A lot of the time, it's simply so I can autofill usernames in a text box, because the website might have the login flow split between pages, and Firefox does not recognize or allow me to select an autofill the username for me. Other times, it's to automatically click through that annoying Microsoft login flow "Keep me signed in? (Don't ask as often)".

For watching YouTube, I use the SponsorBlock addon, because sponsored segments have become very annoying, though some creators have been able to make them actually fulfilling to watch.

On Android Firefox, I also get Disable Page Visibility API. This allows me to use YouTube in Firefox and even background the app and listen to music that way. Plus, with uBlock Origin, I am also able to block ads. I also sometimes install this on different profiles for situations where I believe the web app may try to detect my visibility, such as an online coding test for job opportunities where it will not want me to change windows to look up answers or type code into a compiler (this saved me during a C++ multiple choice exam which asked many times "Which of these is invalid C++?" and "What is the output of [this complicated code block]?").

The below is for my work computers only, because I generally don't need them otherwise.

I will additionally have Firefox Multi-Account Containers and couple that with Simple Tab Groups as I have 6 logins, with one particular site requiring 3 of those logins. I essentially configure the URLs I need to be in certain groups, define one container for each, and then have a couple of default tab groups set as sticky groups that will allow all containers to stay as those containers so I can use multiple sites side-by-side. The interaction with Tree-Style Tab can be a bit janky, especially when configuring new catch tab regular expressions, but usually disabling and re-enabling both Tree-Style Tab and Simple Tab Groups will fix that. Mostly I do this, because my company refuses to fix their SSO breaking due to weird cookie issues, and it's pretty nice to be able to clear cookies for a particular tab group easily.

To clear cookies, and because I do that very often, I use Cookie Quick Manager. I can clear a tab group's entire cookie set by having a tab selected in that tab group, then using "Delete current Context Cookies" and usually that will fix my login issues, and also keep my logins to other sites. For my personal use, I generally don't need to clear cookies, or using a private window, clearing per-site via the web console, or clearing in settings is good enough.

Since I do a bit of web troubleshooting, Modify Header Value is pretty nice. I can call API endpoints that require a subscription key from my browser, even using the web console, and I don't need to worry about figuring out if my headers are correct. I can also get my team to get this add-on so they can do their basic troubleshooting. For my personal computer, I'm much more free to create ad-hoc scripts to test things that I can save somewhere, as sending others scripts in my organization also comes with implicit hours of training and coaching on how to use them (and our leadership has been very sensitive to explicit training hours to get everyone up to speed).

Finally, User-Agent Switcher and Manager for the sites that are built for Chrome, but have worse performance or broken features on Firefox, yet they work fine when Firefox sends them a Chrome user agent. Thankfully, I rarely have a use for this on my personal computer.

If you use youtube a lot, Return YouTube Dislike, SponsorBlock & uBlock Origin. uBlock is still blocking ads on youtube.

Fwiw, this is the kind of thread I used to love The Other Site for. Glad to find one here!

1. Inoreader
2. Bitwarden
3. uBlock
4. Sponsorblock
5. Dark Reader
6. Font Changer
7. Stylus
8. Markdownload - web clipper
9. Lasttab (Alt_Z back to last tab) A. Violentmonkey B. webcompat.com reporter C. Wikiwand D. YouTube Redux

uBlock, Bitwarden, Violentmonkey, Stylus are my top extensions.

Firefox is great mostly on its own, and I only use two extensions:

• uBlock Origin: Enough said.
• Disable Javascript: Works great for getting around a lot of paywalls.

A few I have but haven't seen:

• SVG Export
• Chameleon
• Behind The Overlay Revival
• JPEG XL viewer
• PassLok Image Steganography, which works:

Extensions I use:

• Return youtube dislike
• Search by image
• Simple Translate
• Sponsorblock for youtube
• Ublock origin
• User agent switcher
• Wayback machine
• Youtube audio

Haven't seen so far, so: ClearURLs

• ghostery
• ublock origin

A few that no one has mentioned yet:

• Don't "Accept" image/webp
• Clickbait Remover for Youtube
• Redirect AMP to HTML

If you use Steam a lot:

• Augmented Steam
• ProtonDB for Steam
• SteamDB

Dark Reader is one of my must haves. Turns dark mode on for every site. If a particular site already has its own native dark mode you can turn the extension off for just that site. Not perfect in all cases but works beautifully for most pages you view.

EDIT: Tap To Tab is really good if you are using a laptop without a mouse. Just double tap the trackpad to open a link in a new tab.

• ublock origin
• noscript
• sponsorblock
• greasemonkey

I'm on mobile at the moment, but one I haven't seen mentioned is force allow right click. Super useful for websites that won't allow you to copy images or download a video off their site. Won't always work with the second one, but can if the web developers lazy.

I like to recommend Privacypossum, it returns garbage data to tracking companies: https://addons.mozilla.org/en-US/firefox/addon/privacy-possum/

It would be literally impossible for me to do my job effectively without Sidebery for container management in FF. As someone with multiple accounts used for various CSPs and other services, being able to spin up an environment with no irrelevant cached user sessions is something I depend on heavily (looking at you, Azure).
