Ublock Origin is an obvious one, but I also can’t stand not having Foxy Gestures anymore. It adds customizable mouse gestures, so you can set it up to have easy swipes to go back a page, reload a page, close a tab, etc, and it feels wonderful and smooth to use compared to just using the traditional buttons to do everything. Honestly it’s kinda wild to me that this isn’t more popular now that people are so used to phone gestures. It’s good for the same reasons!
LibRedirect: redirect Website links to alternative frontends like Nitter, invidious, rimgo etc. - couldn’t live without it especially on mobile where using Twitter without the app is really obnoxious
CookieAutoDelete combined with ‘I still don’t care about cookies’: delete cookies the moment you close the tab if not whitelisted, also remove cookie notices and accept all cookies.
Nano Gestures: mouse gestures for navigating websites
How do you get LibRedirect to work on FF mobile? God I hate the Twitter mobile site experience.
You’ll have to use firefox collections with either Nightly or Beta, add the addons you want to a collection and add the collection in ff mobile then you can use the addons. https://www.ghacks.net/2022/10/20/firefox-beta-for-android-now-supports-custom-add-on-collections/
I also had to export LibRedirect settings from desktop and import on mobile because the settings interface is borked (doesn’t show instances to select). There is also Privacy Redirect addon which should work out of the box.
