Dear Ubuntu Developers!
Thank you for your weekly status updates:
As I saw that @3v1n0 backported some patches from Daniel to Mutter, I would kindly ask @oSoMoN, if he could consider backporting a patch as well: https://bugzilla.mozilla.org/show_bug.cgi?id=1623060
I guess that Focal will ship with Firefox 75 on the image and this should help with a better Firefox adaptation to Mutter 3.36 and lead to a better Focal ootb experience.
That patch was too late to be uplifted to Fx 75, but Linux maintainer Martin Stransky is going to backport it to Fedora 31 and 32.
