I’ve figured out how to fix the problem of using Firefox 1.0PR (Firefox .10, which is not the same as Firefox .1, Joanna) with Taylor’s proxy server. Apparently Firefox wants to use NTLM authentication for the proxy server. The is the type of authentication that lets you not type in your password for IE when you are logged on to the campus domain. It basically tries to authenticate your connection by using your windows log username/password. My theory is Firefox first tries to use your windows username/password for each connection, then when that fails, asks you for a username/password.
Anyway, enough techno-babble. To fix the problem:
-Type about:config in the address bar.
-Filter on ntlm
-Change network.automatic-ntlm-auth.allow-proxies to false by double clicking on it.
Now, you should no longer have a popup box for your username/password for every image and page in Firefox 1.0PR.
