The Firefox Configuration Guide for Privacy Freaks and Performance Buffs guide has been updated and more updates are coming. My user-overrides.js was overhauled as well (you'll find a link to it in the guide).
A 'for dummies' version of the guide is nearly complete. It's titled The Firefox Privacy Guide For Dummies! and i had some fun writing it. A new relaxed_user-overrides.js has been created to mesh with the new guide. You can preview that on my GitLab repo.
In a rather important shift, i am no longer disabling First Party Isolation (FPI) in the 'ghacks' user.js, but then i started researching more about FPI and i bumped into this. I have been avoiding the Temporary Containers add-on for some time thinking it really didn't offer much that couldn't be accomplished with Firefox prefs and add-ons i was already using, however reading that thread on GitHub convinced me to install it and i'm testing it now.
Another change to the (advanced) guide is that i dropped Cookie AutoDelete as it is no longer necessary given other changes that were made. With the temp containers add-on, it becomes even less necessary and i'm not sure FPI is making a lot of sense either so i may again disable it. You may want to stay tuned for the next update before incorporating these recent changes.
Here's the full change log for the advanced guide:
- add notice about newsletter subscribing
- corrected advice regarding spoofing the referrer which was suggested for both POOP and uM (now it's enabled in uM only)
- dumped Cookie AutoDelete add-on – not needed when using uM and First Party Isolation, nor are any of these storage cleaning add-ons able to delete IndexedDB storage due to a shortcoming in the WebExt API, which is another reason to enable FPI
falsein user-overrides.js in order to enable First Party Isolation
- added Restrict to Domain add-on to toggle
privacy.firstparty.isolate(FPI) via toolbar button
- removed the list of optional add-ons (NoScript and Smart Referrer)
- minor edits
- coming up: looks like i may be recommending to disable FPI in the very near future and use the Temporary Containers add-on instead – i'm playing with it now
