This is an adaption of the arkenfox user.js for Thunderbird.
Thunderbird roughly follows behind the Firefox ESR (Extended Support Release) mentioned on the calendar. There are no rapid releases of Thunderbird.
Most things that apply to the current Firefox ESR apply to Thunderbird. This wiki will have articles specific to Thunderbird. For general information make sure to see the arkenfox user.js wiki.
If you want to know how a user.js
file works see the rest of the Overview from arkenfox user.js
.
If you're new here, I strongly advise you to read The Thunderbird Privacy Guide for Dummies! as a first overview of this "user.js" ecosystem as long as various interesting integration notes.
