i am setting up a new laptop and trying to import all my current data from my old pc. Nothing is right. It imported alll the shortcuts on my toolbar from years ago. None of these are the current bookmarks from my old pc. ive tried syncing, importing again, nothing works. my bookmarks on my side bar are years old. I dont have ANY of these on my old pc as i deleted them years ago. what the heck is happening and how do i get my new pc browser to look exactly as my old pc looks. This is very frustrating. I have over 500 bookmarks on my sidebar. it looks like every bookmark i have EVER used. This is ridiculous.

You can copy certain files with Firefox closed from one profile folder on the old device to the current profile folder to transfer your personal data. Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.
