The Profile Folder
The profile folder is very important for the xulrunner platform. TomTom HOME stores user settings and extensions in this folder.
Where is my profile
On Windows machines the profile folder is in the Application Data directory on your hard drive. The easiest way to get there is to go to Start > Run... and type %appdata% and click OK. In this folder go to TomTom\HOME\Profiles\xxxxxxxx.default. This is your profile directory.
On Mac you have to open Finder and click your own home folder, usually the one with your name next to it. Within that folder go to Library\Application Support\TomTom HOME\Profiles\xxxxxxxx.default.
Note: the xxxxxxxxx is a random code that is different for every user.
