Why can I scroll up and down on a certain website in firefox and not other browsers? topic

So my work updated their system and now the website I have to use everyday doesn't work on any browser except firefox. In firefox I can scroll up and down but in all other browsers I can't. I've tried all of them from stock to chrome to dolphin to boat, etc.

I really don't like firefox as it is slow and laggy for me. Why is it that it works in firefox and not others.

I think the site is Javascript but I'm not sure as I'm not that technically inclined with that stuff.
