I have a utility that I put together that uses the .NET Framework to capture an image of a web page so that I can use the thumbnail image to preview a page. There are sites which offer this service like websnapr.com, kwiboo.com and shrinktheweb.com. I would like to instead do it myself and leverage Firefox (Gecko) and Safari (WebKit) to render the image.
Is there anything available to do this currently? Is there a C# project that hooks into Gecko and/or WebKit to create images of a loaded web page.
My project is called WebPreview and it uses the WebBrowser control from the .NET Framework, but since that can be a bit outdated the rendered screenshots will not look as accurate as a recent Gecko or WebKit build.

Please post a comment for any Open Source projects which can help me.
I use a Firefox add-on called Screengrab
checkout http://browsershots.org/ its free and open. it says somewhere on the site what plugins and techniques they use...
You can look a this project http://www.codeplex.com/url2jpeg. It uses Internet Explorer.

I'm developing a WPF application using Cefsharp. This web browser inside the app should show some flash contents. I found some forum where the users suggest to use papi flash or pepper flash for Cefsharp.
I have no idea how to implement those plugin in my project.
I'm using the last version of Cefsharp.
Someone can explain how to enable Flash contents in my webview?
Thanks
You need to download the PPAPI version of Flash. Every computer running your app must do the same. Visit http://get.adobe.com/flashplayer/otherversions/ and select FP [xx] for Chromium and Opera where [xx] is the current version number, which is 26 at the time of this answer.
Is it possible to control and instantiate a Chrome browser from C#? Things like opening a new window, changing the URL, reloading the tabs, etc.
I've had a look for a C# Chrome API but can only find a Javascript ones on https://developer.chrome.com/, and the best I could find here was C# - How to control chrome browser - the best answer was to check out the API.
There is an API available for that. It's called 'Selenium', and has a Chrome-specific third party extension.
http://www.seleniumhq.org/
Check that link.
Doing a quick Google search for "chrome C# api" turned up some results I think you may like to consider
I thought the following were particularly promising, if you're willing to accept the concession of using Chrome's developer tools:
Automating Chrome Browser from C#
ChromeDevTools; a C# Library to interact with Chrome's Developer Tools
Chrome Debugging API
Are you looking for something like CEF Sharp?
It's an open source project that allows you to embed Chrome into your .NET application. So you can have those C# controls interact with the browser.
Anyone who has tried Puppeteer? Article about it here. (not C# specific)
I am writing a browser application using C# Language and GeckoFX Browser library.
Now, I want to add the Mozilla Firefox Add-on to my application.
To be precise, I want my application to block undesirable advertisement using AdBlock Plus add-on for Mozilla.
Is it possible to use a Firefox add-on in my GeckoFX control?
Sadly because Firefox extensions are largely based around the interface and working of Firefox's UI, not just the Gecko interface, I don't think it would be possible at all currently to install extensions or .XPI files.
So in order to do this without using an extension, you may have to code an adblocker yourself which I've been trying to do here.
Otherwise, good luck! I've been having similar issues and am looking towards writing my own solution.
I was looking for a way to embed a page that hosts WebRTC video such as the demo from http://www.webrtc.org/demo into a WinForms app so the user doesn't need to install nor launch any external browsers that may contain toolbars, etc, I looked into a few components such as GeckoFX and WebKit.Net but they fail to load the webcam video.
Do you know of any hack or other project that may support WebRTC inside .Net?
Thanks a lot
Chromium Embedded Framework claims to support WebRTC (I haven't confirmed it myself).
https://code.google.com/p/chromiumembedded/

WebRTC is supported by Mozilla Firefox:

If you want to embed Firefox in you project you can easily embed GeckoFX web browser control in your Windows Forms application.
The GeckoFX engine (Mozilla Firefox) says it can use WebRTC. This seem to be right (as far as I have seen yet) but there seem to be a problem with some parts of it. I'm using it actual for WebRTC and have a problem with the video part - see here: Embedded GeckoFx in C#.NET - WebRTC Video not working
Is there a Firefox/Mozilla control for embedding the firefox browser in a C# .net application?
You can have the Gecko rendering engine in the form of GeckoFX.
To quote Google Code:
GeckoFX is a Windows Forms control written in clean, commented C# that embeds the Mozilla Gecko browser control in any Windows Forms Application. It also contains a simple class model providing access to the HTML and CSS DOM.
Even better, there is a fork by hindlemail, actively updated DLL for .Net, here: https://bitbucket.org/geckofx/.
Currently, there are available versions corresponding to Firefox's version 10 and 11.
