zoom.us website does not work in Firefox 48

Simple. The zoom.us website doesn't load on the Mozilla Firefox browser v48 from rapps. Since this is a separate bug to the zoom application itself, 
I will still report this. to check that this wasn't because of the Mozilla Firefox browser (because I very well understand that that type of bug you wouldn't be able to control) I installed Firefox to my actual computer (I ran a virtual machine in VirtualBox) and confirmed that zoom.us was able to work in the Windows version of Firefox. I also checked that the ReactOS Mozilla Firefox browser was able to load other websites, to check if there was a problem with the browser in general, and it did load other websites. I used the nightly version 0.4.15-x86. I will create a new bug report if I see that this bug is also in the stable version 0.4.14.
