Proxy Master - HTTP/HTTPS/SOCKS Proxy Switcher, developed by ngoquangminh200x, is a Chrome extension for managing multiple proxy connections directly in the browser. It provides single-click toggles and protocol support to change how web requests route, while offering bulk import and live connectivity checks to validate lists. The extension targets web developers and privacy-conscious users who need rapid proxy control with local, account-free configuration storage.

What is Proxy Master used for?

Proxy Master operates at the browser level to let users apply proxy routing without installing external helpers, making it suited to workflows that favor in-browser testing and browsing. The extension is available for Chrome and other Chromium-based browsers and presents a compact toolbar popup alongside a settings panel, a layout aimed at keeping proxy controls within reach of regular browsing sessions.

How does it affect browser performance under load?

The extension is described as lightweight and zero-dependency, so background processing is kept minimal compared with external proxy utilities. Running inside the browser process avoids extra helper services, and the popup-based toggle reduces active work when proxies are disabled. Actual impact depends on the number of active proxies and open tabs, since more simultaneous routed connections increase resource use.

Does it keep proxy credentials and settings private?

The developer follows a privacy-focused approach: no account registration and no telemetry means proxy configurations remain local to the machine rather than being uploaded. For authenticated proxies the extension requests webRequest permission so it can deliver username and password credentials to servers, which explains the elevated request access required to support those workflows.

Is it practical for managing large proxy lists and verifying connectivity?

Proxy Master handles bulk parsing of standard IP:Port:User:Pass lists and performs live connectivity checks with integrated country geolocation lookup, plus a real-time display of the current IP and country. Multi-language support across ten languages helps teams in different locales, and the live checks let users validate proxies before routing traffic through them in a Chromium-based environment.

Practical choice for in‑browser proxy control with local-first trade-offs

Proxy Master is a compact option for developers and privacy-minded users who need fast, in-browser proxy switching rather than system-level tools. The trade-off is that configurations live only in the browser environment, so cross-device continuity is not automatic. Tip: back up your browser profile or export proxy lists before moving between machines to preserve your configurations and avoid manual reconstruction.
