Even after all these years firefox keeps using mozilla hidden directory instead of XDG base directories. For how long will this continue?
Watch https://bugzilla.mozilla.org/show_bug.cgi?id=259356 for updates to this request.
~/.mozilla/firefox/<profile> is a mish-mash of data, config, and cache. It’s not simple to unravel that. Beyond that, it would be a breaking change, and that requires more caution.

They could do what Steam does in the short term, which is to move the folder to ~/.local/share/mozilla/* and symlink to ~/.mozilla/*
The reason for doing that instead of symlinking the whole folder is so the configuration could later be moved to ~/.config/mozilla down the line.
