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/ 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.
