FF was running very slow, and after searching online realized I was running a 32 bit version on a 64 bit computer. I downloaded the 64 bit version, created an account and synched - all went well and I was using the cloned version yesterday. Today after restarting my computer the new version reverted back to the initial install page, asking me to create an account or log in, and all my account info (settings/bookmarks/logins) is gone. How do I synch and then keep all info in new version? I'd like to migrate to the new one permanently and delete old version (which fortunately I haven't done yet). Thanks for any help!
