I use share a lot, as i primarily view my RSS/atom feeds on my Android phone and whenever i find something too long to read comfortably on my phone as i hurry about my life, i share it to my computer with Sync. This means i send off 10-12 tabs a day and every time i need to choose the sole computer i have in Sync.

So is it possible to have that computer be pre-selected (so i just have to press send), by Firefox just remembering which computer i last shared something with?
