What is a profile?
Any changes you make while using Firefox are stored in files so that they can be used the next time you run Firefox. These changes can be obvious, like your home page, or changes you've made to the toolbar, but also include things like your history, what sites you've visited, and text you've entered into forms like search fields. They're all stored in the same location, called a profile folder.
These files are kept separately from the program files that Firefox uses to run, which don't change. This means that you can uninstall Firefox without losing your settings, and that if something goes wrong with an update your information will still be there. It also means you don't have to reinstall Firefox in order to clear your information, or troubleshoot a problem.
Where is my profile stored?
Each profile is stored on your hard drive in a profile folder. The default location of the Firefox profile is %APPDATA%\Mozilla\Firefox\Profiles\xxxxxxxx.default\.
- %APPDATA% is shorthand for the C:\Users\<username>\AppData\Roaming\ folder (Windows 7/Vista) or the C:\Documents and Settings\<username>\Application Data\ folder (Windows XP/2000), which depends on your Windows user account name.
Each profile is stored on your hard drive in a profile folder. The default location of the Firefox profile is ~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/.
Each profile is stored on your hard drive in a profile folder. The default location of the Firefox profile is ~/.mozilla/firefox/xxxxxxxx.default/.
