--- Comment #2 from Jacek Caban  ---
Unfortunately we can't use newer code base. Mozilla dropped XPCOM APIs that we
use for embedding Gecko. Even 47 branch required a number of reverts/changes to
make it useful for us. I'm afraid that we will need to continue dealing with
such problems...

On top of that, MS stopped developing IE after version IE11, so that's what
applications expect and we need to target it. Lack of newer HTML features is,
in a sense, good for IE11 compatibility.
