Firefox configuration and extensions

Settings - Arkenfox

I replace the default search engine with my own instance of SearXNG.

I strongly recommend Arkenfox and tweak it to your liking.
Here is my user-overrides.js

Extensions

uBlock Origin
Settings - Filter List - Privacy
Enable
AdGuard Tracking Protection and
AdGuard URL Tracking Protection

Import - Add the Actually Legitimate URL Shortener Tool in uBlock. https://raw.githubusercontent.com/DandelionSprout/adfilt/master/LegitimateURLShortener.txt

If you have Total Cookie Protection on (Strict mode) you can add this to the custom filter list to remove most cookie notifications.

Preferably also enable "I'm a advanced user" and by default block 3rd party scripts and 3rd party frames globally.

Filters
Removing "Members only" videos

Not needed

LocalCDN and Decentraleyes since Enhanced Tracking Protection is set to Strict.
NeatURLs and ClearURLS since we are activating two filter lists in uBlock and importing the Actually Legitimate URL Shortener Tool in uBlock.
HTTPS Everywhere since it's now a built in feature in Firefox.
