I recently purchased a new DELL laptop. My bookmarks from the older DELL laptop did not transfer. Instead under OTHER bookmarks I am getting a hodge-podge of GOOGLE CHROME favorites. I still have the older laptop and the bookmarks I am missing are still there, intact. The older laptop cannot support Windows-11. What did I do wrong, and how do I get the the bookmarks over to the new laptop? THANKS MUCH! Best, Pat Reilly

How did you try to transfer your personal data to the new device?


You can copy certain files with Firefox closed to the current profile folder to transfer/recover/backup your 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).
