FalconLink Extensions makes it really easy to add stuff to the proxy.

Here is an example manifest.json:

{
    "version": "1",
    "icon": "icon.png",
    "id": 123,
    "name": "Cool Extension",
    "images": [
        "image1.png",
        "image2.png",
        "image3.png"
    ],
    "script": "index.js"
}

In this manifest.json, the index.js script will be run. Index.js can access a extension API that allows it to inject content scripts, manage tabs, and more! Here is a basic index.js script that will inject an adblocker:

async function injectAdBlocker() {
    const script = await API.getSrcFor("adblocker.js");
    const tabs = await API.getAllTabs();
    for (var i = 0; i < await tabs.length; i++) {
        if (!(await API.isScriptInjected(await script, await tabs[i].id))) {
            API.injectScript(await script, await tabs[i].id);
        }
    }
}

setInterval(injectAdBlocker, 1000);

Content scripts that are injected can also communicate with the main script through message channels. Here is how you can send a message in a content script:

const channel123 = new ExtensionMessageChannel();
channel123.sendMessage("testing123");

Then you can use this code to recieve the message in your main script:

API.onMessageChannelCreate = (channel) => {
    channel.onMessage = (message) => {
        alert("We have a message!!!: " + message);
    };
}
