A thousand yesses. I have tons of bookmarks and bookmark folders. I have pinned shortcuts because I know I'll visit those sites more often. I even have customized images for them. I lose them each time my computer or laptop go through emergency resets 😕
I miss old shortcut panels. Instead of the pins disappearing and sites swapping for no reason, before I could put them in different rows with empty space between. Now that seems to have disappeared after an update.
Syncing a feature such as shortcuts is an obvious feature. Otherwise - why even bother to develop and tout both sync and shortcuts as added browser feature?
Worse than just not syncing - and I might be wrong - The shortcuts do sync across devices, just not in the users' favor. As of this week a new Linux PC with Firefox installation resulted in removal of the shortcuts on my Linux Firefox laptop installation that I had for at least two years. It looks to me, that sponsored pre-filled corporate shortcuts will override personal settings on all devices during sync.
