uBlock Origin and DarkReader

Recently got into using RSS feeds, so RSSHub Radar was quite useful
Search by Image is good too

• Sponsorblock
• uBlock Origin
• I still don't care about cookies
• Augmented Steam
• BetterTTV
• YouTube Shorts Redirect
• Gumbo
• Bitwarden

These are all the extension I have installed and they are all my favourite tbh. I also have Firefox set to use strongest protection.

• uBlock Origin
• Dark Reader
• Indie Wiki Buddy
• Reverse Image Search
• LibRedirect

Indie wiki buddy. Fandom often times comes on top for most searches, but many games actually have their official wikis elsewhere. This extension hides fandom links for unofficial fandom wikis.

• uBlock
• Privacy Badger
• Language tools (spell checker)
• Mal-Sync (automatically updates Anime & Manga progress with MAL, AniList, Kitsu etc. Supports Netflix, Prime and some high seas website)

Highlight or Hide Search Engine Results

i still use google, so being able to filter out the blogspam and fandom slop is a godsend for usability

• Stylus - I use it to apply some css to make youtube thumbnails smaller because the new huge ones drive me insane
• Plasma Integration - Pretty self explanatory, just makes firefox better integrated with plasma
• SponsorBlock
• UltraWideo - useful for weird content with baked in letterboxing or pillaring

I thought you could only select from a pre-defined list of addons in Firefox mobile?

Making a note to myself about Sponsorblock and chameleon

I may be biased, but I like Lemmy Infinite Scroller. It started out as a 20 minute project just as a proof of concept and then evolved into me trying to make an infinite scroller that works really well. It works well, I can't recall if I made it open-source but I didn't obfuscate the code or anything like that so it's practically open-source anyway even if I didn't make a repo for it. I just published the manifest v3 update of it last week so it's pretty futureproof too.

Other obvious extensions are uBlock Origin, uMatrix, and surprisingly one called Dark Background and Light Text (though Dark Reader is also cool too).
