Firefox (Android): responsive not scrollable

Hello HB-Themes Support,
I’ve discovered a problem with your Aegaeus Theme when using
responsive mode. The theme works as responsive on all mobile browsers
(Chrome, Safari, Opera), except when using Firefox Mobile Browser.
With Firefox my blog is in responsive mode but not scrollable, only the initial top part of my blog is visible.
When I turn off responsive everything works fine as well. Your Demo Page works fine on Firefox.
I’ve also reinstalled Firefox without activating any Plugin.

Are there other users with a similar problem?
