I just installed the Firefox extension SwitchProxy. It looks great, but I just can't load any proxy lists into it, either from a file or from a URL. The files are just TXT files with one proxy per line, format 194.80.38.243:3127, and the URLs are what I took to be "standard", such as http://www.digitalcybersoft.com/Prox...oxy-list.shtml

With files I get a box full of error messages preceeded by "An unknown error occurred", and with the URLs it just says no valid proxies. Obviously I'm doing something wrong, but I can't see what. Anyone?

By the way, http://www.digitalcybersoft.com/ProxyList/ says "The following is a list of Free Anonymous HTTP Proxies checked on an hourly basis", but there is never any list displayed.
