I am migrating to a new computer and would like to use Firefox Sync to bring over all of my bookmarks, tabs, etc. However, though I am logged in on both computers and have everything checked on both systems to share, nothing is changing on the new one. No bookmarks, no settings, no tabs. It's as if nothing is happening at all. I'm not sure if this is not doing anything or if it's just taking a while to sync everything over.
