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.

[Q] How to Make Certain Apps Not Recognizing Your Android Device Again topic

Dear XDA Members, I am using a Taxi Booking App which recognizes my Device each time i try to signup with a new Account. It says " Maximum Number of Signups Reached". I want to do a new Sign Up on that App on the same Android Device .
My Device is rooted . I changed the " Android Device ID" with an app called 'Android ID Changer' . It successfully changed my Device ID as checked in Gtalk Screen. However , that App still recognized my Device.
I also tried changing IP Address by using a VPN App, that also did not work . I have not tried changing IMEI as i was little afraid if that would make my device unstable. Please suggest as this may be helpful on using such Apps/Games which stores your Device Info into their Database.
