Thank you very much for your suggestion.
But it's really a difficult problem to support javascript and FireFox cookies.
Maybe we can find a good method in the future...
Now the only thing to do with the proxies on nntime.com is to leech the js, not the html.
You can find that all the proxies shown on "http://nntime.com/proxy18.htm" are actually in this javascript file:
"http://nntime.com/js/p18.js", which can be leeched by FPL.
So do the following addresses:
http://nntime.com/proxy1.htm -> http://nntime.com/js/p1.js
http://nntime.com/proxy2.htm -> http://nntime.com/js/p2.js
http://nntime.com/proxy3.htm -> http://nntime.com/js/p3.js
