111Proxy - 免费代理切换器和 IP 更换工具 作者： 111Proxy

111Proxy is a free proxy switcher and IP changer for Firefox. It switches Firefox between HTTP and HTTPS proxies in one click, with their usernames and passwords filled in for you, so you can change your IP address and location in seconds.

Sign in to 111proxy: press "Sign in to 111proxy" and log in on 111proxy.com's own page, with your password or your Google account. The proxies you've bought there load into the extension with their logins and expiry dates. The extension never sees your password. While you stay signed in, the list refreshes when you open the extension, or straight away with "Update now".

One switch: pick a proxy and turn it on. The toolbar badge shows the proxy's country while it's on. Turn it off and your normal connection is back.

Test before you use it: the Test button sends one request through a proxy, without switching the rest of the browser over, and shows how long it took and which country it came out in.

Choose which sites use it: send every site through the proxy except the ones you exclude, or only the sites on your list. A domain includes its subdomains. Local and private network addresses always go direct.

Works with any proxy provider, no account needed. Paste private proxies from any provider, one per line, as ip:port, ip:port:login:password or login:password@ip:port, with an optional "# note". Proxies already in the list are skipped.

Also: logins hidden until you click the eye; click any value to copy it; copy a proxy in three formats; days left and a Renew link for proxies from your 111proxy account; a My IP tab with your IPv4 and IPv6 address and country; optional tab reload and cookie or cache clearing when the proxy changes; 15 languages; light and dark themes.

Limits: HTTP and HTTPS proxies only; SOCKS5 proxies are skipped on import.

Privacy: your proxies, logins and settings stay in the extension's storage on your computer. To show country flags, the extension sends IP addresses to 111proxy.com's lookup; the My IP tab asks api.ipify.org for your address. No browsing history, no analytics, no ads.
