I own a website where I offer free proxylists.
I want an addon which allows the user to change the proxy in Firefox by clicking on a link on my website.
When the users don't has this addon installed he should be redirected to a URL of my choice.
Because I have different types of proxies on my website, it should be able to set socks 4, socks 5 and http proxies.
I don't need a GUI, it should just be functional.
