Go to one of the others on the sync. If its data is intact,

Type about:support in the address bar and press enter.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

This is your current profile. Copy the folder As Is to a folder on a thumb drive. Then Copy the folder to the new system.


These can't get your data back but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox
