[Javascript] Why is firefox acting lazy?

[trojani2000 at hotmail.com (Troy III Ajnej)]

I'm having trouble with firefox while atempting to change the source 
of an iframe using javascript.  
1.
I've discovered that it will change it only if I restart the browser. 
"Refresh" is doing nothing!
 
Is there a way to force firefox refresh the iframe content?
 
(I'm currently testing my attempt to change the source of an iframe
in fx 1.5)
 
2.
I've noticed that fx 2.0 is acting very slowly in some repetitive java-
script instructions that fx1.5 and<, were handling decently.
 
Does anybody know why is this so, -everybody expects improvements
in newer versions of software?
 
Thanks in advance
