What do you mean by switching it? Did you move your profile folder(s)? Did you following the procedures described here: http://kb.mozillazine.org/Moving_your_profile_folder (advanced)

Also, what version of Windows are you running?

Note: You may want to make a backup of your profile folders in case they get corrupted during this process. The location varies based on your version of Windows. See: https://support.mozilla.org/kb/profiles-where-firefox-stores-user-data#w_finding-your-profile-without-opening-firefox

(1) What version of Windows?

(2) Was it one of these?

C:\Program Files\Mozilla Firefox\ C:\Program Files (x86)\Mozilla Firefox\

If so: Did you update your desktop shortcut to connect to the new location? If you right-click the shortcut, choose Properties, then the Shortcut tab, it needs to point to the new location of firefox.exe.

Note that Firefox will still use the default location for the profile folder in the AppData\Roaming (main profile) and AppData\Local (cache) as specified in the profiles.ini file. You may want to use the Profile Manager to create a new profile folder on the D drive and move personal data to that new profile and subsequently use the Profile Manager to to delete the old profile and remove its files. Be sure to check if the new profile works before deleting the old profile or backup its content to the D drive.
