Change location Firefox

To change the location of your Firefox-profile folder (or to move it to another computer):

Copy the folder of your profile to the new location (the folder mostly has a random name. you can look it up by opening the profile manager (see down))
Open profiles.ini in the firefox program folder (c:\program files\… on Windows), and change the location of your profile folder.
Other paths also need to be adapted in ini-files in the profile folder. This is because Firefox uses absolute paths and no relative paths. Use a text-tool to look up the ini-files where the folder locations are stored.
Try to run Firefox with the profile manager. If things don’t work out (eg: if your profile looks wrong or incomplete); remove the following files in the root of the profile folder. The next time firefox starts, it will recreate these files with the correct file paths.

To launch the profile manager (linux):

firefox -ProfileManager
