User-Agent: Mozilla/5.0 (Mobile; rv:46.0) Gecko/46.0 Firefox/46.0 I found Firefox Sync in the settings app today. I don't recall ever seeing.it there before... Nice, I've been looking forward to it. Unfortunately, it doesn't seem to work. When I click the first time, it shows an intro page. I click "get started". On the next page, it tells me that my account is empty. However I know I sync at least two machines via my account. When I click "sync now", it takes me back to the intro page. Now, the "get started" button won't work for some period of time.
