Step 3: The Troubleshooting Information page opens. In the first column, look for the Profile Folder label, and then click on the Open Containing Folder option next to it.

Step 4 . Once the folder is open, locate and click on Profiles in the address bar.

Use the Run dialog box

Step 1. Make sure the Firefox application is closed.

Step 2: Press the Windows + R keys to open the "Run" dialog box.

Step 3: Type %appdata%\mozilla\firefox\profiles\ in the address bar and press OK.

Use the Run dialog box to locate the Profile Folder

This will open your Personal Folders.

Step 1. Connect the external/USB drive to the old computer.

Step 2: Right-click the folder and select Cut.

Step 3: Locate your external/USB drive, right-click on it, and select Paste.

Step 4. Now you can unplug the external/USB drive and connect it to your new computer. Make sure that the new computer recognizes the external/USB drive, and that Firefox is closed.

Step 5: Open the external/USB drive folder, and then copy the Profile folder.

Step 6. On the new computer, find the Firefox profile folder using any of the methods in Part A.

Step 7: Right-click in the folder and select Paste. If Windows alerts you that files with the same name already exist, choose Replace.

Restart your computer and check Mozilla Firefox to make sure that the browser profile has been updated.
