Firefox

Dark Reader, LibRedirect, LanguageTool, TreeStyleTab, Return YouTube Dislike, uBlock Origin, Decentraleyes, DeArrow, Auto Tab Discard

In addition to ublock,
I would also suggest

• decentraleyes
  Stores commonly used librarys localy,
  instead of downloading them from a third party.

• clearURLs
  Removes tracking parameters from links.

• google search fixer
  Shows the more advanced search features,
  That firefox for Android currently doesn't get

• video Background Play Fix
  What the name says,
  Good when you use youtube in the browser.

One that is more specific to Lemmy, which I am working on

While this is extension is mine and I have an obvious bias, I am using the extension constantly for my personal use as well. Might be nice for others too :)

Facebook Container, if you're like me and feel forced to use that godawful site because all your friends are still there.

Plus another vote for uBlock Origin (I have a feeling that one will come up a lot).

My 2 cents:

• LeechBlock - for blocking distracting websites on schedules
• Unhook - for hiding YouTube recommended videos, comments and other distractions
• Privacy Badger - for blocking trackers

• My O'Reilly Downloader - if you have an account already, but want to persist some material to peruse at a later time
• TreeStyleTab
• ContainerProxy - I have mullvad running in gluetun container on my desktop PC, and it exposes HTTP proxy endpoint over Tailscale, so I can have VPN for my webbrowsing, without having to connect. This does not give me full protection, but I use tailscale a lot, and it doesn't play well with Mullvad.
• I Still don't care about cookies

• uBlock Origin
• ClearURLs
• Bitwarden
• ReturnYoutubeDislike

Ublock Origin and Adblock Plus
