2. set your project to x64

3. add this to Program.cs:

 Xpcom.Initialize(“Firefox64”); 

4. drag geckowebbrowser control to your form.

5. add this to form1_load:

 geckoWebBrowser.Navigate(url); 

That's it.

Long:

1. create a new Winform application in Visual Studio. Mine is VS 2019 as of now.

2. Go to Nuget. search Geckofx. find the latest version, which is v60.

   Install Geckofx60.64

   Once this is done, you will see some changes in your project:

   • A Winform control is added to your UI Toolbox

   • A list of DLLs are added to your bin/[debug |release]/Firefox folder

3. Drag a GeckoFX UI control to your Winform Designer, make it dock well as you wish:

4. You need add this code to the Program.cs:

 Xpcom.Initialize(“Firefox64”);

Run the app, it should crash or pop up with an exception!

5. To solve this, you need to create a new config for x64 architecture, like this:

6. To open a Url in GeckoFX browser, use this function:

 geckoWebBrowser.Navigate(url); 

Rebuild and run the app, hooray! It worked!

To embed Gecko browser in your winform application, you need:

• XulRunner: XULRunner is a Mozilla runtime package that can be used to bootstrap XUL+XPCOM applications that are as rich as Firefox and Thunderbird. It provides mechanisms for installing, upgrading, and uninstalling these applications. XULRunner can be downloaded here. Choose the version you like.

• GeckoFx .net assembly file, which you can download from here. Also choose the correct version which matches the XulRunner version.

• Unpack the GeckoFX-330.zip, you will get below files:

• Add references to the dlls as shown above, click browse and select the Geckofx-Core.dll and Geckofx-Winforms.dll

• In the toolbox, right click, and then select “Choose Item”, select Geckofx-Winforms.dll, and the Gecko winform control will be shown in the toolbox

• Drag a GeckoWebBrowser control to the winform designer, and let’s call it “browser”

• In the form1.cs file, add below code:

The line Gecko.Xpcom.Initialize(@”..\xulrunner”); specifies where the xulrunner runtime is located. In this case, we put it into a folder (@”..\xulrunner”).

Now run the application, yeah~~~
