Browser incompatibility - FireFox,Portable Edition 2.0.0.6 v/s IE6.0

[yo4]

Hi all,
am getting lots of headache in trying to solve the problem below:

I have a jsp page where there is a button which opens a pop-up window.
I've also defined a function in javascript where a short-cut can be used to display the pop-up window and i've stored the function on a separate js file.

The problem is that it is working perfectly on IE but on Firefox there is a pop-up blocker which does not allow the window to be displayed.
Note that while clicking on the button on the firefox, the pop-up is displayed.

please help...thanx:)

"The problem is that it is working perfectly on IE but on Firefox there is a pop-up blocker which does not allow the window to be displayed."

Both IE and Firefox incorporate pop-up blockers (which may or may not be enabled by the user of course) but which cannot be over-ridden by the script.
