If you had problems with your old profile and haven't identified what set of files is causing your problem, it's recommended you copy files from your old profile folder to the new one in several steps, testing whether things are still working okay between steps. Extensions, themes, and preferences are a common cause of Firefox problems so you should re-install any extensions and themes and reconfigure your preference settings if you had problems with the old profile, instead of trying to transfer them. It's recommended that you only copy data that would be a lot of work to recreate (such as bookmarks, passwords, and cookies) to the new profile. Make sure that Firefox is completely closed before you copy data to the new profile. Firefox will create any additional files it needs when you actually start Firefox with the new profile. You can then copy the files containing the data you wish to transfer to the new profile folder. You can exit the Profile Manager at this point and a new profile folder will be created (if you don't open Firefox with the new profile, the newly created profile folder will be an 'empty shell'). Make note of the name you give to the new profile so you can distinguish between the old and the new. If you haven't yet created a new profile, completely close Firefox by choosing File -> Exit (or Quit) and then open the Profile Manager and follow the prompts to create a new profile.
