Raw camoufox binary

[bestplay9384]

Hi,

I've looked through code & commits in repo, very good work! :) However no matter i try i cannot start the browser correctly.

What am i trying to accomplish? I've built a docker container based on AmazonLinux2023 (fedora), installed every package that was missing and needed by camoufox (docs). Now i'm trying to start camoufox-bin, but via code. All my code is in NodeJS that is why i cannot use Camoufox python library (and this is a must have unfortunately because all my scraping scripts (300+) are based on puppeteer-core interfaces - NodeJS).

What i tried? I've thought there is a chance to start camoufox like that:

1. Define CAMOUCONFIG[\d+] ENV variables with NodeJS by breaking config JSON into parts as launcher code does it.
2. Run raw camoufox-bin/launch via code (puppeteer.connect / puppeteer.launch) (with args: --remote-debugging-port 9223 -headless)
3. Binary starts up with websocket debugging port opened and puppeteer connects to it.

*** You are running in headless mode.

4. This is the place that code is stuck and after some time it timesout from puppeteer itself, it looks like browser disallows to control it via websocket or something. I've also tried to run binary manualy via NodeJS child_process.exec but effect is the same.

ProtocolError: browsingContext.create timed out. Increase the 'protocolTimeout' setting in launch/connect calls for a higher timeout if needed. -> at BidiBrowserContext.newPage (in puppeteer context)

Am i missing something? I've noticed there is no firefox profile in my args, but still it should start up with some defaults imho, am i right?

Last question, are You planning maybe to release binary itself as a standalone firefox "fork" so playwright nor python are necessary?

Amazing work, thanks for help :)

Hello,

Camoufox uses Playwright's Juggler protocol to control the browser, which is implemented separately from Firefox's native RDP API. Since Firefox's remote debug server is detectable (see #90), I don't have plans to support Puppeteer any time soon.

---

If you're looking to use Camoufox in NodeJS, you could launch a remote server using the Python library (see here), then connect to it from NodeJS Playwright:

import playwright from "playwright-core";

// Connect to the Python server
const pwEndpoint = `ws://localhost:36539/bf81a6ed494f6ecf3698ca7570506203`;
const browser = await playwright.firefox.connect(pwEndpoint);
const context = await browser.newContext();
const page = await context.newPage();

Hope this helps :+1:
