11.11.14 Today Aurora updated to the new Developer version, which is awesome! Except, all of my sync information was lost (bookmarks, add-ons, settings, etc). I tried to set up the sync again, and learned that there is a new version of sync in which you have to create a new account. I created a new account, but that obviously doesn't solve my problem because all of my sync information disappeared once the update was applied. I have been searching the forums and cannot seem to find a solution. I have gone to https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ to find an older version of Firefox to install, sign into sync (old) in order to retrieve my information, then upgrade to my new sync account, but I am not sure how to navigate this directory. Can anyone help me find the installation file for the latest version of Firefox just before the developer version for Windows 8.1? Or if you also have this problem or know of a solution for it, some advice would be much appreciated! Thanks!
