One-Click Proxy von aahil

One-Click Proxy lets you switch a proxy on or off from the toolbar with a single tap. Add your proxy's hostname, port, type (SOCKS5/SOCKS4/HTTP/HTTPS), and optional username/password in the extension's settings page — all fields start empty, no proxy is preconfigured.
When enabled, your browsing traffic routes through the proxy you configured; when disabled, you browse directly. Proxy credentials are stored locally in the browser and used only to authenticate to the proxy server you specify — nothing is collected or sent anywhere else.
