I can not sync. I click sync but nothing happens. I have a old mac and a new one. I want to sync because I want to bring over the settings from the old mac to the new one. I click sync but absolutely nothing happens.

How do I Begin by saving my current settings on my old Mac to the sync function so I can bring them over to the new Mac?

How do I bring over the info from "sync" to the new Mac? None of this is working for me. I need help please. thanks

If Sync isn't working then you can possibly transfer the files directly via a removeable USB drive.

You can copy certain files with Firefox closed to the current profile folder to recover or transfer personal data.

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.
