Thanks for telling me about the incompatibility with Firefox, will look into that. I don't know why the options box comes off-screen, works for me, so I'll try using your CSS on different resolutions - that may be the problem...? I'll make the text come after the checkbox (I'm not the best in design and user interaction ;p). I'll make it so that the checkboxes fill from the settings. But could you clarify the last bullet please? I don't exactly get what you say - are you saying there should be an option to disable all the features? And I'll see what I can do about the MSE profile change.

@BrockAdams Thanks - added that in the latest version :)

@BrockAdams Thanks for that - I've fixed it and updated the post :)
