I'd love to use Firefox, but I've been missing three (subjectively, for me) important features:

1. vertical tabs (now happening, yay!)

2. either tab grouping or workspaces (brave/edge vs. vivaldi style)

3. easy sync-and-restore of tabs/groups/workspaces across my devices

Do you know of a good solution for 2 and more importantly, 3?
