[Mediawiki-l] Browsing wiki page in Mozilla FireFox opens the FIle Open Dialog Box

[Uniyals]

Hi,

I have created a wiki site for my project documentation. Its running on
Windows XP, IIS5.1 and MySql and PHP 5.2.

Now When I open the wiki site in IE 6 or greater the site works perfectly
fine. All the links works.
But when I open my wiki site on Mozilla Firefox the Main Page load fines but
after clicking on links it starts to show up
the Open FIle Dialog box  (shown in the attached file.).

Need help in fixing this problem.

Thanks for the help in advance.
