Snap is a really cool system and in some ways it's better than Flatpak. I understand the maintainability benefits over repo-packaged software. But, consistently, Snap-packaged software Does Not Work; Chromium broke when they snapified it, and now Firefox is broken on @ubuntu too.
I can't report bugs against it, because the support page for Mozilla is useless and the distro doesn't accept bugs against the snap version - even though, from a user perspective, the change is simple. "Firefox on Ubuntu used to be really good, and now it doesn't work."
I don't know what to say other than, Canonical, you broke my heart. I've been a die-hard Ubuntu user since Lucid - on my first ever computer of my own! - and I think I'm done.
I'm getting a Lenovo 2242 NVMe SSD for my T480 in today, and I think I'm going to install Fedora.
@tindall I've been using Mint for 9 months now, and it very consistently worked for me without many issues at all. Maybe that's a distro you might want to look into, also it's compatible with Ubuntu packages.
