Bookmarks lost after changing password?

more options

Hello, I reinstalled my OS X and downloaded Firefox. I forgot my FF account password so I changed it. After that, my bookmarks and passwords did not update after logging into FF.

I followed the Mozilla instructions for restoring my bookmarks but the only date listed was today's date.

I feel after resetting my password my data was lost.

Any help is greatly appreciated.

Thanks.

Sorry, but when you changed the Password for your Firefox Account (used by Sync and some other services that Mozilla provides) all your data was wiped from the Sync server. The old Password was used to generate dual "keys" under which your data was encrypted for 'transit' to the Sync server and while on the Sync server. The new Password created different dual "keys" which couldn't de-crypt your data; thus the Sync server wiped that useless data.

Sync is not intended to be used in lieu of a proper Firefox data backup with a solitary device, like when reinstalling the operating system. With a 2nd device connected to your Sync account your data could have been "recovered" from 2nd device when that device was connected to the SYnc server with the new Password; then your data would have been sync'd to the device with new OS installation & and new Firefox installation.

Mozilla.org has several separate sections. Each has its own login/password.
