I have made a site that allows for some basic Active Directory management remotely. This is done using vbscripts and ActiveX.

The site works fine on IE.

However, now I want the site to work on Firefox and Chrome browsers (The goal is the use the site from an Android tablet).

I understand that vbscripts and ActiveX will not work. What is the best way to go about rebuilding the site so that it will work with Firefox and Chrome?
