Our website is designed to pop up a window (through javascript function) when user click some buttons. Client has allowed pop up from our website, but after a while with popup serveral times, popup blocker starts to block popup from our website. I doubt that there are some hidden settings within firefox, even i have disabled the popup blocker, after a while, it starts to block. I must restart Firefox to let it work again.



Reproducible: Always

Steps to Reproduce:
1. Disable popup blocker or add your website to the exception list
2. Pop up a window within a javascript function
function A(){B();} function B(){popUp();} somebutton.onclick = A;
Actual Results:  
It will work for a while, but after several times, the popup blocker starts to work. Note that i have disabled it.


I think there may be some hidden setting in Firefox, but since Firefox has opened the popup blocker setting to users, it should at least work as what we have expected.

I can confirm this bug; here is a reproducible case:

1.  Disable the popup blocker
2.  Load this url in the browser:  http://people.mozilla.org/~jgriffin/membuster.html
3.  After a short delay, this will start opening 30 new windows, then close and reopen them until 319 window opens have occurred.

Results:
After 20-24 windows have been opened, a message appears stating that Firefox is blocking popups (usually about 10 of them), before the windows start opening again.  This sequence repeats until the end of the test:  20-24 windows open, then 9-10 are blocked.  This occurs with the popup blocker disabled.

This occurs due to a pref dom.popup_maximum, which defaults to 20.  Should this pref be active when the popup blocker is off?
