Please input your http proxy list into the free proxy checker. The online proxy checker accepts different formats.
All the browsers (chrome, firefox, ie, opera, safari and others) support the proxy option. When you set a proxy in browser, the proxy will fetch the web pages for your browser. The webistes regard the IP of proxy as your IP so it cannot trace your real IP. We recommend using Elite Proxy Switcher to set proxy for your browsers.
You can use our free software Elite Proxy Switcher to test the proxy speed. We don't check the speed of the proxies. It's because one proxy may have different speed for different users. For example, a proxy which is fast for USA users may be slow for European users. So check it by the software.
