is there a reason why these methods tend to be static rather than on this
particular browsercontext?

[jam, 2016/03/02 17:50:37]

that's the (admittedly awkward) pattern used here. browsercontext methods
implemented by the embedder are virtual methods. methods that interact with it
and are implemented in content are static.

this should be split into two interfaces.. but probably a lot of this will go
away once the mojo refactorings are gone
