I am accessing the web trough a proxy. The thing is that since I'm logged into a domain, the domain user I have has restricted proxy access. However, If I use a different user to log into the proxy I do get access since this user has no proxy restrictions. I finally was able to use this different cproxy credentials by using control keymgr.dll on windows, as far as I understand it basically logs using the stored credentials when attempting to go to some site (in this case myproxy.whatever.com) The thing is that If i use firefox to browse, it apparently attempts to use the domain user/ password when accessing to the proxy so it has restricted access. So I can think of two solutions, but I need help so here are the questions: Solution a).- How to force firefox to ask for authentication cedentials when accessing to the proxy? Solution b).- How to use the keymgr.dll credentials (same way that IE does) to firefox when attempting to access proxy? or, possible solution c).- how to and where to store proxy credentials for firefox?
