Firefox showing pop-up always?!

[TM13]

Hi,

We use Cisco Ironport so when i open my mozilla  firefox, it is asking username and password, we use allowing proxy link  on IE on security/intranet but it is won't work on Mozilla, also it is  showing always below pop-up on Firefox, is there any solution for it?

"This  web page is being redirected to a new location. Would you like to  resend the form data you have typed to the new location?"

or try to do this

Type in your firefox url : about:config

Then toggle the following option : network.http.prompt-temp-redirect

How about that asking username/password everytime?
