Firefox freezes for few seconds while syncing new bookmarks. Happens everytime I add a bookmark or when I change a folder's place. Everytime I bookmark some site, firefox syncs it right away, which is good in a way. But it takes a few seconds (around 5 secs) and whil FF syncs the whole window freezes. Means nothing responds anymore, not to a click nor to a roll over or scroll. It's quite annoying actually. So I'd say : FireFox should run this sync in background of other tasks, seamlessly. If FF cannot run this sync in background of other tasks, is there a way to tell sync ton only sincronize just before quitting or such ? OR, is there a way to quickly shut sync down and activate it back up when needed ? Thanks for the answers to this time consumming problem.
