You are reading this blog because you are using Firefox 3.0 and you are behind the proxy which needs authentication and you are annoyed by the frequent prompts for the username password.
How to stop this?
1) Just type about:config in your address bar
2) Enter network.auth.use-sspi in the filter field
3) Change the value to false if set to true
You will never be prompted anymore (may be you have to enter for the first time after making this change)
