copied!<p> This can be done quite easily via a Chrome extension, using the <a href="https://developer.chrome.com/extensions/webRequest" rel="noreferrer"><code>webRequest</code></a> API. The example below blocks <strong>all</strong> external scripts. Replace <code><all_urls></code> with a <a href="https://developer.chrome.com/extensions/match_patterns" rel="noreferrer">more specific pattern</a>. For very dynamic patterns, you can modify the <a href="https://developer.chrome.com/extensions/webRequest#event-onBeforeRequest" rel="noreferrer"><code>chrome.webRequest.onBeforeRequest</code></a> event listener.</p> <ol> <li>Create a new directory.</li> <li>Create the files below.</li> <li>Load the unpacked extension in Developer mode via <code>chrome://extensions/</code></li> </ol> <h2><code>background.js</code></h2> <pre class="lang-js prettyprint-override"><code>chrome.webRequest.onBeforeRequest.addListener( function() { return {cancel: true}; }, { urls: ["<all_urls>"], // Change this to a more specific pattern types: ["script"] }, ["blocking"] ); </code></pre> <h2><code>manifest.json</code></h2> <pre class="lang-js prettyprint-override"><code>{ "name": "Block request", "version": "1.0", "manifest_version": 2, "background": { "scripts": ["background.js"] }, "permissions": [ "webRequest", "webRequestBlocking", "<all_urls>" ] } </code></pre> <p>PS. Keep an eye on the <a href="https://developer.chrome.com/extensions/declarativeWebRequest" rel="noreferrer"><code>chrome.declarativeWebRequest</code></a> API. At the time of writing, it's in the beta/dev channel, but when you read this answer. This new API is more efficient than the <code>webRequest</code> API, and allows one to use <a href="https://developer.chrome.com/extensions/event_pages" rel="noreferrer">event pages</a> instead of background pages (the <code>webRequest</code> API cannot be used on event pages).</p>
