Some notes on what I have tested so far: - the firefox flatpak isn't affected
- running directly the firefox binary from the snap, unconfined (without snapd mediation) doesn't exhibit the problem - I incrementally upgraded components in an impish VM (where the problem isn't observed), getting them from jammy: - wayland 1.20.0, still works - mutter 41.3-1ubuntu1 (along with libglib2.0 2.70.0, gnome-keyring 40.0, libgcrypt20 1.9.4), still works - mutter 42~beta (along with libc6 2.35, pipewire 0.3.38, libinput 1.19.3, libwacom 2.0.0), still works - gnome-shell 41.3 (along with gjs 1.71.1, mozjs91 91.7.0, icu 70.1, gsettings-desktop-schemas 41.0), still works - gnome-shell 42~beta (along with libadwaita 1.1.0, gsettings-desktop-schemas 42.0, gtk4 4.6.2, pango1.0 1.50.4, yaru-theme 22.04.3), breaks So the regression seems to be evidenced when upgrading gnome-shell from 41.3 to 42~beta. I took a look at the diff, but it's quite large and I couldn't spot anything obvious. On a hunch, I reverted the new screenshot UI in gnome-shell 42 (rebuilt packages locally), but it didn't make a difference. ** Summary changed: - Cannot rearrange Firefox (snap) browser tabs/bookmarks in Wayland sessions + Cannot rearrange Firefox (snap) browser tabs/bookmarks in gnome-shell 42 (Wayland session) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1964541 Title: Cannot rearrange Firefox (snap) browser tabs/bookmarks in gnome-shell 42 (Wayland session) Status in Mozilla Firefox: New Status in firefox package in Ubuntu: Confirmed Bug description: Since 42~beta-1ubuntu1, and still present in 42~beta-1ubuntu2, attempting to re-arrange tabs in Firefox fails.
