🔥 Extended Config

For advanced users who would like to go above & beyond when protecting their privacy & security, at the cost of occasional breakage, Phoenix offers an Extended configuration. For a list of features specific to Phoenix Extended, please see here.

Tip

Unlike Phoenix's standard default configuration, Extended is profile-specific. This means that you can use the Extended config as needed when you desire the extra protection, and revert back to Phoenix's standard config through another profile for everything else.

Personally, if you're up for it, I would highly recommend trying out the Extended config, and setting overrides as needed.

Tip

Phoenix makes it very easy to set overrides through your about:config. No more manual override files!)
