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.
So, it seems the XSS filter has issues again with https://www.facebook.com/tr/, see #22362 (moved). It freezes again on sites that have this URL embedded,e.g. on http://zeit.de.
This is with NoScript 5.1.4.
