Recently, Gnome Extensions integration is suddenly broken on Slowroll after a zypper dup
.
I have to manually install gnome-browser-connector
; in contrast, no intervention is needed on Tumbleweed.
Meanwhile, Slowroll is still on Gnome 47, which has no compatibility issue at this point, while Tumbleweed causes some Gnome extensions to be disabled because they haven't caught up with the API changes yet.
That said, they are still one of the top rolling distros which will save your setup/customization time in the long run.
So, you probably have to pick your poison.
