How to Get Firefox Settings From an Old Hard Drive to Windows 7by Mircea Gabriel Suciu
By restoring your Firefox settings from an old profile you will recover your important bookmarks and browsing history. This will save you plenty of time, as you will not have to manually look for this data. Firefox does not provide a way to automatically export and import profile data, but you can use the file manager on Windows to copy the profile data manually from your old hard drive to your new computer.
Connect your old hard drive to your computer. If this is an external hard drive, plug it into one of the USB ports. Alternatively, if the hard drive is not external, open your computer's case and connect it via an IDE or SATA cable.
Click the Start button, type "Computer" and select "Computer" from the list of results.
Navigate to the user folder on the old hard drive's partition where the operating system is installed. If the hard drive has Windows XP installed on it, this folder is located under "Documents and Settings\username." If Windows 7 or Windows 8 is installed instead, the user folder can be found under "Users\username," where "username" is the name of the Windows account.
Navigate to "AppData\Mozilla\Firefox\Profiles," click the profile folder found in this location and press "Ctrl-C."
Type "%APPDATA%\Mozilla\Firefox\Profiles\" in the search bar of the Windows File Manager and press "Enter" to access the location where Firefox profiles are stored in your Windows 7 installation.
Press "Ctrl-V" to transfer the old Firefox profile settings to your new account.
