+# How to test a Chrome Extension
+_Contributors: [Dario Kondratiuk](https://github.com/kblok)_
+
+## Problem
+
+You need to download an use an specific browser version.
+
+## Solution
+
+Thank to [Google for testing](https://developer.chrome.com/blog/chrome-for-testing). Now finding and downloading a specific version of Chrome is easy.
+
+You will find the available versions [here](https://googlechromelabs.github.io/chrome-for-testing/known-good-versions.json).
+Once you have the version you want, you can download it using the `BrowserFetcher` class.
+
+```cs
+<!-- snippet: CustomVersionsExample -->
+<a id='snippet-customversionsexample'></a>
+```cs
+Console.WriteLine("Downloading browsers");
+
+using var browserFetcher = new BrowserFetcher(SupportedBrowser.Chrome);
+var chrome118 = await browserFetcher.DownloadAsync("118.0.5993.70");
+var chrome119 = await browserFetcher.DownloadAsync("119.0.5997.0");
+
+Console.WriteLine("Navigating");
+await using (var browser = await Puppeteer.LaunchAsync(new()
+             {

+{
+    await using var page = await browser.NewPageAsync();
+    await page.GoToAsync("https://www.whatismybrowser.com/");
+
+    Console.WriteLine("Generating PDF");
+    await page.PdfAsync(Path.Combine(Directory.GetCurrentDirectory(), "118.pdf"));
+
+    Console.WriteLine("Export completed");
