Cannot restore backup

I had taken a manual backup of my firefox data as i needed to get my laptop formatted. I had copied the entire contents of the "...AppData\Roaming\Mozilla" folder onto my external HD. I have tried to follow the steps as mentioned in this article: ( but it has not helped at all. I believe i was using FF 12 before taking the backup, but i maybe wrong.

Therefore, i have a couple of questions: 1. Is there any way of knowing which version of FF was i using? 2. If not, will that affect whether i can restore FF to the earlier state.

I essentially want to restore FF to the last state i left it in, including bookmarks, preferences, plugins, etc. Please help!

(I am using FF 3 just for now. I intend to use 12/14/15 after i can restore the thing)

Re: Cannot restore backup

The version of Firefox that you use doesn't have any impact on your backup (so long as it's 3.6-15). So if you've backed up the Mozilla folder in the APPDATA/Roaming, you can just paste the into the same location on your computer, install Firefox 15, and you can continue using Firefox.

If you restored the profile folder and not the matching profiles.ini file then you need to use the Profile Manager to create a new profile and choose the location of the restored profile as the location of the new profile (Choose Folder).
