I tried syncing my phone to my PC, but it doesn't work. None of my bookmarks, homepage, passwords, etc. show up on my phone. Why? How do I get the sync to work?

The latest version of Firefox includes a new Sync. In order to use the new Sync you need a firefox account. Check this link out. https://support.mozilla.org/en-US/kb/how-to-update-to-the-new-firefox-sync
