AMO currently uses the original Share Icon, now a trademark of Nextumi. Given that the icon has been subject to takedown requests in the past, it's probably a good idea to use the Open Share Icon instead. (de facto standardization is good)
It also helps that the symbology of the Open Share Icon (two hands sharing an item or a "look at this" eye) is probably easier to explain to non-technical users than the node graph of the original Share Icon.

Osunick: Should we do this? I vote yes.
Any update on this one?
Been wanting to do this for awhile: r56717.
Verified FIXED on https://preview.addons.mozilla.org/en-US/firefox/addon/3481.
A similar looking logo is trademarked by ForeScout Technologies Inc. Would this pose a problem?
