Firefox's about:support page lists the about:config prefs that have non-default values ("Important Modified Preferences"). That includes prefs you've changed and internal prefs changed by Firefox code.
- nominated1 7y agoUnfortunately the info provided by about:support doesn’t separate changes made via the gui and changes made via about:config. It also includes settings that may have been altered by Add-ons. Another benefit to using a user.js file is that your changes are persistent. If Mozilla changes a setting via an upgrade, like they did with experiments and plan to do with DoH, your changes aren’t overridden.
