Chrome Proxy Extension

Simple Chrome extension that enables a fixed proxy (SOCKS5/HTTP/HTTPS) and lets you define the domains that should go through the proxy.

Features

• Toggle proxy on/off from the extension action button.
• Store proxy URL in sync storage.
• Manage allowed domains list (proxy only for these domains).
• Context menu item to add/remove current domain.

How It Works

• The background service worker reads the proxy URL and applies it via chrome.proxy.settings.
• Allowed domains are stored in chrome.storage.local and used to build a PAC script that proxies only matching domains.
• The options page lets you set the proxy URL and manage the domain list.

Setup

1. Open Chrome and go to chrome://extensions.
2. Enable Developer mode.
3. Click Load unpacked and select the project root folder.
4. Open the extension Options page and set your proxy URL.

Proxy URL Format

scheme://host:port

Supported schemes: socks5, socks5h, http, https.

Example:

socks5://127.0.0.1:1080
