Are all the changes made manually in Edit -> Preferences (or about:preferences) saved -only- to prefs.js? My plan would be to start a vanilla FF, modify the preferences I wish, see what is changed in prefs.js compared to vanilla one, and make user.js from seemingly meaningful rows.

I suppose this does not work at least for preferences where something has to be searched or installed, like a new search engine or so.

I'm using FF 65.0.1.

Most, but not all.

For example, if I change mailto in Applications from "Use Thunderbird" to "Use Gmail", then that option is saved in the handlers.json file.

The search engine options are saved in the search.json.mozlz4 file.
