popup troubles

[Rashmi]

Whenever I launch Mozilla Firefox, different adult sites opens up automatically with new window in background. This is much annoying , as these sites continuously keep opening up even when I removed the cookies and enabled the block popup option. So far I haven't been able to find any way of stopping them from opening up . I guess I would have to dump Mozilla Firefox, which I have used so far.

Don't know how to get rid of these..

To further what Dick posted, this is an infection on your system, not in Firefox. You would be getting the same popups no matter what browser you use. In fact, I would venture to guess that the popups may even be coming from IE right now...
