GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
When interacting with Moat via about:preferences#tor, clicking the Submit button has no effect. Pressing the Enter key does work.
@brade and I first noticed this while working on tor-launcher#40002 (closed), but this bug is also present in the 10.0a5 candidate builds as well (on macOS at least).
