Everytime I start Firefox 4.x on a browser/Windows 7 PC I have to setup Sync. Even on the original browser. Is there a setting that is wiping out my sync settings? I do like to clear most of my stored data (history and such) when I close the browser, is one of those settings causing Firefox Sync settings to get erased? I also use Google Chrome and Google Chrome's sync just plain works. Maybe Firefox developers could figure out how Chrome's sync works and copy that implementation...
