Just to be sure please back up your bookmarks. Because this addon is editing bookmark information directly. If the browser crashes while the add-on is manipulating bookmarks, the bookmark information may be wrong.
User reviews
this extension can delete all of your bookmark names. (no I'm not talking user error, I'm talking about the titles being completely lost, it's not supposed to do this, but it glitched out and the app enabled permanently even though I uninstalled it

at first I thought it forced you to not have any title labels, but it actually has an option to add it's own titles, just edit the name as you normally do, but sadly whenever you enable or disable, the titles are lost :(

LIFESAVER!
I've got a LOT of bookmarks in my toolbar, I don't understand why the compact (icon-only) format is not implemented in FF natively.
Thank you so much for this extension!
