Hi, the buttons in the Firefox Sync tab are completely useless.. Nothing responds and this happens only in Firefox 4, works perfectly in 3.6.10.. Its been like this ever since i upgraded to 4 ever since 4 came out but i never had to touch the settings cuz it continued to work properly despite the useless Sync settings tab.. And now for the first time it's giving this error and i can't do anything about it-"'''''Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action'''''." Its still working fine on 3.6.10 btw. It's been like this for the past 2 days.. Help? :-/
