Just wanted to repost this because it's still an issue. I'm on VPN and can connect to any site with Firefox because the browser has a built-in proxy setting. Safari uses the system-wide proxy setting and sometimes it works, sometimes it doesn't. In fact, I can enter a URL in both Firefox and Safari and it will load immediately in Firefox and in Safari, it may take several minutes to load or not load at all. Clearly Safari does not handle proxies correctly. Anyone else notice this issue?
