Browser extension

The Proxmint Proxy extension sends your browser’s traffic through your own Proxmint product with one switch. Pick the product, the exit country and whether you want a new IP for every connection or the same IP for 10, 30 or 60 minutes. The extension answers the gateway’s login itself, so the browser never asks for a proxy username and password, and the popup shows your exit IP once it’s on.

It runs in Opera, Chrome, Edge, Brave and other Chromium browsers from version 120. The listings on Opera add-ons and the Chrome Web Store are in review, and this page will link them once they’re live. The code is plain, unminified JavaScript under the MIT licence.

1. Buy bandwidth for a product on the pricing page. It’s sold per GB with no subscription and never expires.
2. Open the extension from the toolbar and press Sign in with Proxmint. A tab opens on proxmint.com; sign in if asked and press Connect. That creates a read-only API key named “Browser extension” and hands it to the extension, so there is nothing to copy. Prefer to paste a key? Make one under Settings, the same key the customer API uses.
3. Pick a product, a country and an exit IP option, then press the power button. The toolbar badge shows the country code (or ON for any country) while the proxy is on. Changing a setting while it’s on reconnects with the new one.

This section is the extension’s privacy policy. In short, it keeps your key on your device and sends nothing anywhere except what running the proxy needs.

• What it stores. Your API key, your settings and the proxy login of the product you turned on, in the browser’s extension storage on this device. Nothing is synced to other devices. Sign out in the popup deletes all of it; revoke the key under Settings to retire it for good.
• What it sends to Proxmint. The API key, only to proxmint.com, to read your products, how much bandwidth each has left and their proxy login.
• Sign-in page. The extension runs a small script on one page only, proxmint.com/extension/connect, to receive the key you create there. It reads nothing else on that page or any other.
• Your browsing. While the proxy is on, the browser sends your traffic through the Proxmint gateway, except local and private addresses and proxmint.com itself. The gateway handles it under our privacy policy. The extension itself never reads or changes the pages you visit.
• Exit IP check. Each time you connect, the popup loads Cloudflare’s www.cloudflare.com/cdn-cgi/trace once through the proxy to show your exit IP and its country. Cloudflare sees the proxy’s IP, not yours.
• No tracking. No analytics, no ads, no remote code, and nothing is sold or shared.

Why it asks for each permission:

• proxy: to turn the browser’s proxy setting on and off.
• webRequest and webRequestAuthProvider: to answer the gateway’s login request with your proxy login. Login requests from any other proxy or site are left to the browser.
• browsingData: when you switch location, the browser would keep sending the login it cached for the old one. The extension clears that cached login for the gateway’s address only; your cookies and data for every site, proxmint.com included, stay as they are.
• Access to all sites: the gateway’s login request arrives on whatever site you load first, so the extension has to be able to answer it there.
• storage: to keep your key and settings between browser sessions.

Questions go to support@proxmint.com.

• Only one extension can control the browser’s proxy at a time. Turn off Opera’s built-in VPN and other proxy extensions first; the popup says when another one is in control.
• The extension targets countries only. For a state, city, ZIP or ASN, build a proxy line with the targeting options and use it in a tool that takes a proxy login.
• A browser proxy doesn’t hide everything: WebRTC can still show sites your own IP. For separate identities per account, use an antidetect browser; the integration guides cover the common ones.
• If pages stop loading, the popup says why when it can. The usual causes are a product out of bandwidth or a country with no free IPs right now; the error codes page lists the rest. A short list of sites is refused outright (see blocked websites).
