Bought a new computer? You may need to transfer the program data on the old computer to the new computer. However, Firefox, as a popular browser in the world, has a very large number of users, so many people wants to know how to transfer the Firefox browser profile file (including bookmarks, history, passwords and add-ons) on the old computer to the new computer. Of course, there are many ways to accomplish this task.

If not, you can also copy the profile file to the new computer and import it. Let’s take a look at how to transfer the Firefox profile file to the new computer.
