+1 for Tumbleweed, it works so incredibly well. In the very rare case where an update doesn’t work out for you, you can easily roll back to a previous btrfs snapshot.
Fedora is quite nice, too, but I’ve come to prefer rolling distros over a release based one.
Kalpa / Aeon might be interesting, too, if your use case fits an immutable distro.
It’s so unfortunate that Firefox on Android, for some reason, never worked well with password managers (as I understand it, it doesn’t support the APIs that Android has for them). Sometimes it’ll trigger the manager, more often, it won’t. Infuriating and a deal breaker for me.
I’ll give it another go, maybe this has been improved recently.
Edit gave it another crack, gosh, it actually works now!
