I updated my computer from Windows XP to Windows 7. It creates a folder called windows.old, but I am unable to locate the old Firefox bookmarks profile. Where can I locate this or was it deleted in the upgrade?

Copy the file bookmarks.html from

C:\Windows.old\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\<old profile>\


C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<new profile>\

Somewhere in these paths should be the user name, shouldn't it? I think it is where the double slashes are: From \Windows.old\Documents and Settings\YourUserNameHere\Application Data\Mozilla\Firefox\Profiles\ To c:\Users\YourUserNameHere\AppData\Roaming\Mozilla\Firefox\Profiles\\ – Martin Jan 28 '10 at 15:46
The username was always there but I played a bit with the formatting and some markers removed the <username> part. – Snark Jan 28 '10 at 16:09
Okay, I already guessed that. – Martin Jan 28 '10 at 16:12
Right, I expected to find it there, but there is no 'Application Data' folder! Where would the upgrade have moved that, or would it delete it? – WilliamKF Jan 28 '10 at 16:23
You must enable the display of hidden and system directories – Snark Jan 28 '10 at 16:40

I actually use a Firefox add-in called X-Marks (also works for IE) that stores your bookmarks to their server, allowing you to sync your bookmarks across machines (and also useful when upgrading a machine). It won't help you if you didn't use it before you upgraded, but it could be useful for others who dont want to go through the same trouble.

You can restore everything by just copying your previous profile from

C:\Windows.old\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\



. Then, edit the file profiles.ini



Replace XXX.default with the name of the profile folder.
