Different browser, different appearance

Hi,

I am using the Chrome browser for webflow. The design of my site looks fine when I open up the live site in Chrome. See screen shot:

But when I open up the live site in Firefox, the second button is not in the right place and there is a white space under the 2nd picture. See screen shot:

Not sure how to fix this since it shows fine in one browser and it doesn’t in another. Does anyone have any ideas?

You can view the read-only version here: Webflow - GS Market Media

Any help is appreciated.

Thanks!
