Firefox

Dark Reader - Seriously why can't more sites have a "don't blind me" mode in this day and age.

https://addons.mozilla.org/en-US/firefox/addon/darkreader/

Swift Selection Search - It has a little configurable pop up whenever you highlight a word so you can send it to any number of destinations... search web, search youtube, search imdb, send to translate, look in wikipedia... you just build the search function in the extension and it becomes a little icon in the dialog box.

uBo - besides the obvious, it's good for eliminating unwanted design elements from a site.

https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/

Simple Tab Groups - it lets you define groups of tabs as sort of work spaces. I have ones for cooking, working, hobbies... you just configure what you want and dump all the tabs you want into it then you can switch to them like presets. Very handy when you open lots of stuff for a project.

https://addons.mozilla.org/en-US/firefox/addon/simple-tab-groups/

Auto Tab Discard - gives much more granular control of what tabs are slept or set to never time out and how quickly they do that. Good for keeping memory footprint lower if you use a lot of tabs.

https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/

Augmented Steam - links to isthereanydeal.com so that whenever I'm viewing steam pages on browser for a game, it's showing me all the current best deals from sellers.

https://addons.mozilla.org/en-US/firefox/addon/augmented-steam/

ScrollAnywhere - more robust click to scroll feature. Let's me use a button to scroll and pan sites more like a touchscreen device while using my mouse.

https://addons.mozilla.org/en-US/firefox/addon/scroll_anywhere/

BitWarden - cross platform open source password manager

https://addons.mozilla.org/en-US/firefox/addon/bitwarden-password-manager/

I really like the Firefox Multi account containers extension... It keeps my school stuff out of my shopping stuff, and my banking stuff separate. I keep all Google products in their own container.

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

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 - RSS reader with filtering capabilities

Redirector - auto-redirect specific URLs (for example, changing a YouTube Shorts url into a regular one, or changing Reddit links to always go to Old Reddit)

Undo Close Tab Button - adds a list of recently closed tabs to the tab context menu and allows you to restore them (including the tab's history in the back button) (max amount = browser.sessionstore.max_tabs_undo)

Violentmonkey - using userscripts that allow you to change things on websites.

• For Instagram - unmuting videos + setting their default volume
• For YouTube - disabling the subtitles/captions + disabling "autoplay next" for playlists + disabling autoplay of channels homepage video
  • a way to disable specific keyboard shortcuts (you need to manually add the code as a new script). I use /^(Key)?(End|I|O)|(Digit|Numpad)\d$/ instead of /^(?:Digit|Numpad)\d$/ (thanks to this post), to also disable the End/I/O keys in addition to the number keys. (note: this can also be used for other sites, but you might need to change stopPropagation to stopImmediatePropagation, for example on Patreon)
• Note that, at least for Violentmonkey, if the userscript doesn't have the "://" part of the url in the @match line then you need to add it in the userscript settings after installing the script (for example, if the @match line of the script only has *.youtube.com/* then put *://*.youtube.com/* in the "@match rules" line in the settings)

YouTube Comment Reader - allows you to search through the comments of a video (by clicking on the addon in the Extension menu and then clicking on the "YouTube Comment Reader" at the top or the "X Comments" at the bottom of the tooltip)

Page Shadow - allows you to use dark and light themes on sites that don't have the option to change it.

And if you're like me and you find that some YT videos feel too slow but 1.25x is too fast, then you can use Enhancer for YouTube's "Playback speed" feature to have smaller speed steps. Then you can hold ctrl and use the scrollwheel (while over the video) to change the video's speed by the amount you chose (I use 0.05 speed variation, mostly changing to 1.05x or 1.10x)

AdNauseum. Built on uBlock Origin.

Block all the ads so you never seem them, but click them all so the advertisor pays.

CamelCamelCamel

Price tracking for amazon. Find out if deal are deals, or "we doubled the price last week and made it 25% off".

On Android, I use Redirect AMP to HTML and the essential uBlock Origin.

On desktop, I use MarkDownload to quickly convert and format webpages and snippets of text in markdown format.

Sponsorblock and blocktube.

Sponsorblock lets users designate when there are ad reads on YouTube and will automatically skip over them.

Blocktube allows you to block YouTube channels wholesale so you don’t have to see people like Mr. Beasts stupid face if you open a private window or some such

Cookie AutoDelete • I have it set to delete any cookies unless I whitelist/graylist the site

DownThemAll! • I really don’t use this much anymore, but it really saved time when I needed it

Link Text and Location Copier • I can’t live without this.

NoScript • I only temporarily enable specific domains on each site I visit, but some sites get permanent whitelisting

uBlock Origin • How does anyone browse without this?

F.B Purity • I have this in a separate profile now for those rare times I have to reach out to family or some group only has a Facebook page, but it’s not enable in my main profile anymore

I'm new to it, but I'm really enjoying libredirect so far.

Tree Style Tab

Trees are awesome

https://addons.mozilla.org/en-US/firefox/addon/behind_the_overlay/

Removes a lot of those annoying signup pop-ups with a simple keyboard shortcut or mouse click.

• uBlock Origin
• Indie Wiki Buddy
• Dark Reader

By install order wherever I get a fresh install for some reason:

uBlock Origin

Cookie Auto Delete

Dark Reader

Decentral Eyes

Privacy Badger

YouTube enhancements:
Sponsor Block

DeArrow

Return YouTube dislike

uBO of course.

Sideberry

Tree Style Tabs has helped me organize and declutter my FF window. Very customizable.

Keepa.

It shows a graph, under every Amazon product page, showing what price changes have gone on in the past several months. There is also options to be alerted when the price goes to an amount you can set yourself.

Easier to get the cheapest prices on Amazon, if you don't mind waiting sometimes. Sometimes you genuinely find a product that's the lowest price it has been in years, but at least with Keepa you can see that for yourself.

besides ublock I only really use darkreader

Foxy Gestures, Zoom Page, Consentomatic and Bitwarden and UBO, of course.

Ublock Origin, NoScript, Chameleon, Libredirect, DarkReader, OneTab, Stack Overflow Prettifier, Classic Mode For Wikipedia, Vimium

Ublock origin Bitwarden Bypass Paywalls Clean - Via github Privacy Badger Notes

Here are my favorite Firefox extensions—these are a mix of essentials I can’t live without, privacy tools, and some that just make browsing a lot easier:

Essentials:

uBlock Origin: The best adblocker out there. It’s fast and blocks ads, trackers, and more, which keeps things running smoothly. KeePassXC-Browser: Integrates KeePassXC to auto-fill passwords—super handy so I don’t have to type anything in manually. To Google Translate: Great for quick translations. Just highlight text, right-click, and you’re good to go.

Privacy & Security:

ClearURLs: Cleans up tracking elements from URLs, so when I share a link, it’s cleaner and more private. Firefox Relay: Creates alias emails to protect my real address, helping keep spam away. Privacy Badger: Blocks trackers automatically as I browse—set it and forget it. LocalCDN: Prevents my browser from connecting to third-party servers unnecessarily by using local resources instead. Consent-O-Matic: Fills in those annoying cookie consent forms for me, saving time while keeping my privacy settings intact.

Enhancements:

Dark Reader: Turns on dark mode for websites, perfect for late-night browsing. Augmented Steam: Improves the Steam store by showing better prices, deals, and user reviews. FoxScroller: Auto-scrolls pages, so I don’t have to keep manually scrolling long articles or threads. Save Page WE: Saves web pages as HTML, which is awesome for viewing them offline or archiving stuff. Download All Images: Lets me bulk download all images from a webpage—super useful. Simple Tab Groups: Keeps my tabs organized in groups so my sessions don’t get messy. Plasma Integration: Integrates Firefox with my KDE Plasma desktop for native notifications and media controls. Add custom search engine: Lets me add any site’s search bar to Firefox as a custom search engine for quicker searches. I mainly use this for SearXNG.

VPN:

Windscribe: My VPN extension for a secure connection with just one click.
