[Feature request] Add to the right-click menu

[MattDemers]

Hey all.

I apologize if this is messy; I'd just like to request that the extension be added to the right-click menu for a page (it isn't there, at least on Firefox). Would prefer this to having to manually click the extension button in the top-right. Wallabag and Pocket had/have similar buttons, and it's just an alternative workflow.
