Hi, Trying to move profiles to new computer.

Can only B/U some parts to usb stick, then get error message that filename paths are too long, not supported in system (win 7).

Tried creating folder in stick w/ profile name & then copy contents of appdata folder to that. Same problem.

Also tried copying main folder to root of C/ drive...same issue.

Rebooted & retried, same.

What's Up Doc?...thanks

Setup sync on the old computer. Then log into the Firefox on the new computer, sign into sync, and watch the magic.

You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder. You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
