Firefox 29 removed the ability to "send tab to remote device". Namely, you could send a share intent from any other app (select "share", select "Firefox", select any other Firefox Sync device you want to send the tab to) and a few seconds to minutes later it would appear e.g. in your desktop Firefox as a new tab.
That was my main use of Firefox on Android. How do I get exactly that back?
That is, I want send tabs from an Android share intent to Firefox on the desktop! Not the other way (I do have FoxToPhone, but hardly ever use it). It should be a one-click operation, I don't want to copy/paste URLs, I don't even need a target device selection (although I would be okay with the two-click operation required in Firefox 28), because I always want to send to the same device.
This should work even when the Android device is offline (plane), in which case the tabs should simply be queued and sent when the network comes back (that's exactly what Firefox 28 did).
The use case is everything I spot on mobile (from emails, interesting stuff while browsing, reading articles on Pocket, etc.) but that maybe doesn't work on mobile (Flash), requires more screen estate or just requires some kind of action from me, which I don't want to perform on mobile.
