The first bug I found in Synchronize It!, version 3.1.1306, is the error message:
"1 error(s): The operation completed successfully"
Well, this message is suitable for masochists...
But seriously, Synchronize It!, when copying %AppData%\Mozilla\Firefox\profiles to c:\favorites.zip, it wants to copy fc1juz9z.default\GoogleToolbarData, too, but fails to do that giving the error message, which amuses me, leaving me in a positive mood.
