Redundant Extensions
The arkenfox user.js wiki discusses browser extensions and recommends keeping them to a minimum because they have privileged browser access.

About Redundant Extensions
This wiki page from the arkenfox user.js project provides guidance on Firefox privacy and security extensions. It advises keeping extensions to a minimum and organizes them into recommended, optional, tools, and "don't bother" groups.
Recommended entries include uBlock Origin with blocking-mode and filter-list setup and Skip Redirect. Optional entries include Header Editor and container extensions. It describes many other extensions as redundant with built-in protections such as Total Cookie Protection, HTTPS-Only Mode, or uBlock Origin, and notes that Temporary Containers and Redirector are no longer maintained.
