How to use PuppeteerSharp (v 18.0.1) with Firefox?

Hello,

I'm currently using PuppeteerSharp's 18.0.1 version in a .NET 6 application. I've been using it with Chrome, but wanted to try it with Firefox. However, I failed to find any recent documentation explaining how to do it.

This is my code:

var browserFetcher = new BrowserFetcher(SupportedBrowser.Firefox);

await browserFetcher.DownloadAsync();

var launchOptions = new LaunchOptions()
{
    Browser = SupportedBrowser.Firefox,
    Headless = true
};

var browser = await Puppeteer.LaunchAsync(launchOptions);

var navigationOptions = new NavigationOptions()
{
    Timeout = 60000,
    WaitUntil = new WaitUntilNavigation[] { WaitUntilNavigation.Load, WaitUntilNavigation.Networkidle0 }
};

var page = await browser.NewPageAsync();

await page.GoToAsync("https://www.google.com/", navigationOptions);

This results in a timeout during the call to GoToAsync with following error:

PuppeteerSharp.NavigationException: Timeout of 60000 ms exceeded
 ---> System.TimeoutException: Timeout of 60000 ms exceeded
   at PuppeteerSharp.Helpers.TaskHelper.<>c__DisplayClass6_0.<WithTimeout>b__0() in /home/runner/work/puppeteer-sharp/puppeteer-sharp/lib/PuppeteerSharp/Helpers/TaskHelper.cs:line 53

   at PuppeteerSharp.Cdp.CdpFrame.GoToAsync(String url, NavigationOptions options) in /home/runner/work/puppeteer-sharp/puppeteer-sharp/lib/PuppeteerSharp/Cdp/CdpFrame.cs:line 108

What am I doing wrong? Is there some documentation regarding Firefox for me to base myself?

The latest Firefox version changed some CDP stuff. I will publish a new version today.

I just shipped 18.0.2 fixing the Firefox download.
