The in-game browser isn't something anyone can really update unfortunately. The code is controlled by the game, as far as the UI is concerned you make the window that goes around it but the actual browser is a black box. Daybreak would need to update it, or wikia would need to stop breaking it with all their ad code... don't hold your breath in either case.
You used to be able to get around some of the issues if you could get logged in and use the old monobook skin, but they dropped that option earlier this year.
