Auto login to proxies?

I have a huge list of private proxies and I tired of typing in the same username and password ever 10 minutes. Is there something that well save a default login and auto login every time?

You can use software like Proxy-Firewall (http://uniqueinternetservices.com/proxy-firewall-download.html) to easily switch proxies. Just enter your user/pass once during configuration.

If you have a static IP address or your provider has a way of detecting your dynamic IP address, you can be authenticated by your IP if your provider know how to do this. There is no need for a user/pass with this method of authentication.

I was more looking for a IE plugin, is there anything like that?
