I'm troubleshooting this page: http://fujixerox.com.sg/promotion
On Chrome, when I resize the window width, the header and menu changes accordingly.
But on Firefox (42.0), as I resize, the header and menu doesn't resize accordingly.
I don't have access to the template, so I can't edit the head tag.
I can only edit the content in the div with the "lyt-main" class.
How do I ensure that the header and menu behaves correctly in Firefox?
