Firefox Beta 7.0 (1893) 1. Go to Firefox settings and login into sync with an existing account which was not used recently (in the last hour). 2. Confirm the sign in using the emailed confirmation link. 3. Check the sync section in the Firefox settings page. Expected: The sync should automatically start after confirming the sign in. Actual: First sync is not automatically initialized. Note: If the sign in does not need confirmation, first sync works as expected. It's automatically initialized after logging in.
I can reproduce on my iPad. This needs investigation in 7.0.
