Firefox 159.0.1 (Mozilla .deb) now uses ~/.mozilla instead of ~/.config/mozilla – only me?

mrpg

I am using Firefox (.deb from mozilla, not snap) in ubuntu budgie 26.04. It used ~/.config/mozilla/firefox as its profile root but after I updated to 159.0.1~build1 and clicked on a link in Thunderbird it began to use ~/.mozilla. I closed firefox, renamed that .mozilla directory, and it recreated it. MOZ_LEGACY_HOME is not set, and XDG_CONFIG_HOME is unset.

Is it only me? Thanks for your time.

I found out what happened. It is because I had a file called mozilla, that triggered the creation of ~/.mozilla

(My mozilla-deb 159.0.1 still points to ~/.config/mozilla/firefox however I don't run Thunderbird in that VM so I can't check for any interactions…)

If you (apt) install, say, firefox-nightly that will set up a new profile, where that one ends up? (from about:support and about:profiles, not just the profile path, but also cache, update, crash and similar directories?)

Thanks:

about:profiles

Profile: default-nightly This is the profile in use and it cannot be deleted. Default Profile yes Root Directory /home/m/.mozilla/firefox/kxzeul1f.default-nightlyOpen Directory Local Directory /home/m/.cache/mozilla/firefox/kxzeul1f.default-nightlyOpen Directory

about:support Profile directory /home/m/.mozilla/firefox/kxzeul1f.default-nightly /home/m/.mozilla/firefox/Crash Reports /home/m/.mozilla/firefox/Pending Pings /home/m/.cache/mozilla/firefox/kxzeul1f.default-nightly/startupCache/startupCache.8.little

I tried firefox and nightly in a new VM, both used .config, they didn't create ~/.mozilla so I think I should blame TB.
