IE tab will not allow you to use ActiveX on Linux because ActiveX is Windows only. You could look at running Internet Explorer under WINE. Ideally you want to look at using something that does not depend on ActiveX. A lot easier said than done of course. A company that produces a product that relies upon ActiveX is a company that doesn't care about customers using platforms other than Windows.

I think the closest SUSE office to Pakistan is in India.

If you go to there is a link near the bottom 'Get a quote' which gets you a form you can fill in to request someone from SUSE contacts you.
