''fredou_79 [[#question-1197779|said]]'' <blockquote> I have created a firefox account to transfer my favorite, passwords and so on from my browser to a fresh install on it. I was dismayed to not have firefox synch anything to my browser when I logged in my account on the fresh install. I have connected it to my laptop to test it and it synchs only new bookmarks I have made on my fresh install... Could please help me to find out why it doesn't synch my stuff. </blockquote> Sorry, Sync isn't intended to be used in that manner - i.e., as a backup medium. You should have included that laptop in the Sync process '''''before''''' doing that fresh installation. Or you should have done a true backup of your Firefox data beforehand. https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
