I doesn't even honor its name Rated 2 out of 5 stars

YES, I can send any link I found on any page, NO I CAN'T SEND ANY TAB, and that's what I was looking for. It should be as simple as it is in the mobile version: share---> Firefox Sync---> XXDevice. And I still wonder why this feature isn't already in Firefox Sync for desktop as it is in Firefox for Android.

This review is for a previous version of the add-on (0.5.1-signed).
