Tips

By default, your profile will be stored in "C:\Documents and Settings\ username \Application Data\Mozilla\Firefox\Profiles". You may specify a different location by clicking "Choose Folder..." - read the warning below if you do this!
- You can set Profile Manager to open whenever Firefox starts by un-checking "Don't ask at startup". Leaving this box checked will cause Firefox to use the previously selected profile when started.
