After downloading Firefox, I neglected to drag the app into the applications folder and have been using Firefox by opening the dmg install disk image each time. If I finally drag the app to the applications folder, and eject the dmg install disk, will my browsing data be intact and available once I open the version in the applications folder? Thank you, World.

Firefox comes in two or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And one folder in the profile of each user on the computer.

If you remove the Firefox folder, the user folders would not be affected.

Make sure that Firefox gets installed properly.

Open the Firefox disk image file and drag the Firefox program into the Applications folder on your hard drive. You shouldn't double-click the Firefox application to run it from the disk image, but instead drag it out of the DMG folder.


Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you uninstall and (re)install or update Firefox, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.

In Mac OS X v10.7 and later, the ~/Library folder is a hidden folder.
