Mull at least has been fixed in the divestOS repo. I can’t speak to fennec as I don’t use it.
The version in the f-droid main repo is behind because of Mozilla changing their repo system thus screwing with the build process and at least for now currently requiring a compiler that doesn’t meet F-Droid’s (IMO slightly ridiculous) standards for allowable software.
That looks useful, I might host that. Does anyone have an RSS feed of at risk data?
