Cannot Sync to new Computer

Hello!

I have bought a new computer recently and for the life of me cannot seem to get the history/passwords/bookmarks to sync to it despite using Firefox Sync. I have enabled these items to be synced, checked that cookies are on, closed and restarted both my computer(s) and firefox multiple times as well as everything else laid out in forums here.

Can anyone help me port my bookmarks over to my new computer?

Thanks.

You can use a portable USB stick (drive) to transfer your personal data to the new device.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
