Firefox profiles are similar to user accounts in the Windows operating system. Just like the Windows operating system, Firefox uses accounts to save user data. In Firefox, user accounts are called profiles.
A profile includes user information such as passwords, bookmarks, preferences, history, and other data. In addition to the default profile, you can also create more profiles if you want.
Mozilla Firefox saves all profiles in a location different than its install location.
If you want to backup passwords, bookmarks, and other data without using any additional software, you can simply create a copy of your profile folder before reinstalling the Windows operating system.
In this guide, we will see how to open the Firefox profile folder in Windows 10 and earlier Windows versions.
