I have formatted my computer's HD because of a problem with Windows 7, the thing is that Windows 7 didn't start, so I couldn't backup my Firefox settings, bookmarks, plugins, themes, personas and etc. the right way. I also don't have a Firefox Sync account. What I do have are all the folders and files of Firefox, because I just created a new partition and installed Windows 7 again, what I'm having trouble is finding a way (if there's any) to restore everything from my previous installation to the new one. I have searched for days on both Google and on te Firefox forum with no success, the only questions I found are about restoring a profile, but what I'm trying to do is the same thing that the Firefox add-on " FEBE " does, which is restoring everything to the previous configuration. Here's alink to the add-on: https://addons.mozilla.org/pt-br/firefox/addon/febe/ I have tried copying, pasting and overwritting from the " .default " folder to my new installation of Firefox (yes, Firefox was closed), but when I opened it again, nothing was restored. I every single folder and file Firefox ever created on my computer, this includes the installation folder (at Program Files), the profile (.default at AppData) folder, the Mozilla folder (ProgramData) and the Mozilla Firefox folder (also at AppData). I also had the FEBE add-on installed, but like stated before, unfortunately I couldn't start Windows 7, forcing me to create a new partition to install a new copy of the OS. Thanks in advance. PS. Sorry if I made the text too long and/or if I mentioned the same things twice, just trying to be thorough.
