Anyone else have this problem?

Every time I test proxies (like with ProxyFirewall 1.0.4) when it's a list of like 300 proxies that people say are all working, in proxyfirewall it says only like 5 of them are working? And it's always the ones in malaysia etc.

I add them under open http proxies and do a normal check with a 15 timeout etc.

So what exactly is going on here?

5/100, hey that's above average!
Welcome to the world of public proxies

I'd say : that's a normal thing, you're one among thousands to abuse that public proxy
