Can't log in to Firefox Suync on new computer

I'm trying to get my new laptop set up, which includes moving all my bookmarks/settings over from the old one. Theoretically, I should be able to do this with Sync. However, it's taking several hours for the security code to be sent, which means it's long expired before I ever see it.

Is there some way to get that code before it expires?

(Please note the time/date stamps in the attached screenshot.)

If Sync isn't working then you can transfer data directly using a removable USB drive.

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).
