I have this problem on one of my project pages.
When I test the page on Firefox browser I discover that the horizontal scroll-bar is enabled where I can scroll horizontally with the same width of the page taking into consideration that the problem is appearing only on Firefox.
Any recommendations?
Here is the page that I am working on.

And below are some pictures to describe my case!



You have a
text-indenton thesendinput button, in the last row of your table for the contact form. It’s currently set to2000px– set this to-2000pxand the horizontal scrollbar will disappear in Firefox.
