Consider arkenfox compatibility

[calhix]

Hello, love the app so far, have you thought of seeing what preferences are able to be kept from arkenfox? Just thought I'd experiment and I can't even view anything just yet, may or may not be worth it.

While these prefs would be good to incorporate into the application, I am worried they could break compatibility with some websites. Maybe I should add an option to build an application with custom prefs.
