If a page will not load in webkit, you can use the Chromium Embedded Framework (CEF) option in our Device Automation editor. Please see more in Knowledge Base Article # 3035481. Sometimes, there are pages that will not load in the webkit browser for various reasons especially unsupported features. It emulates Mozilla Firefox, earlier versions of Google Chrome and Microsoft Internet Explorer. Webkit is the default browser engine used in our normal editor for loading webpages.

To be able to load this page in the application, I defined a SchemeHandler and named it "chrome:". The "Downloads" page of the application is a "clone" from the Chrome Browser which is an HTML page stored in the "storage" folder. Google Chrome uses HTML interface for Settings, Downloads, Extensions and other pages so I did the same for the "Downloads" page. SchemeHandler: This handler helps to load the web pages that start with "chrome://". An interesting extra feature of this context menu is the "Save as Pdf" option which does not exist in Google Chrome. MenuHandler: I added the items from the Chrome Browser which I use most to the browser context menu. LifeSpanHandler: CefSharp calls the OnBeforePopup function of this handler before it opens a pop-up window and it tells CefSharp to open it in a new tab and not in a seperate window. The application uses Ctrl-F4 to close the active browser tab so this handler helps to inform the application that Ctrl-F4 was pressed in the browser. KeyboardHandler: When the focus is on the CefSharp browser, it "eats" all the keys pressed by the user. #Chromium browser downloadHere is a list of the CefSharp handlers and what they do:ĭownloadHandler: Tells the application when a new download starts and about the progress of the ongoing downloads. Handlers are used to make CefSharp to "behave". Tor is initialized by calling the InitializeTor function which is an exact copy from the Tor.NET sample application. Chrome is generally located in a folder like the following one:Ĭ:\Program Files (x86)\Google\Chrome\Application\.111īut keep in mind that, if you are really concerned about your privacy, you are not recommended to use Flash when using Tor because Flash plugins might reach the Internet bypassing your proxy. If you want to use Flash in your browser, you can copy the PepperFlash folder from your Chrome installation to the application directory and uncomment the PepperFlash related line. We make the CefSharp component to use our Tor proxy by adding the "proxy-server" command line argument. SchemeHandlerFactory = new SchemeHandlerFactory() SchemeName = SchemeHandlerFactory.SchemeName, Load pepper flash player // ("ppapi-flash-path", appPath new CefCustomScheme The following is the CefSharp initialization code.ĬefSettings settings = new CefSettings() However there are some interesting parts in the code which may be helpful for curious coders. The application is a WinForms application with only one form. You can check if you are really connected to the Tor network by clicking the "Check if Tor is active" button. "DuckDuckGo" button opens the alternative DuckDuckGo search engine with a ".onion" Tor address. "Downloads" button opens the downloads page. When Tor is ready to use, the address bar goes pale green. When the application starts, it connects to the Tor network and starts the HTTP proxy. It is a standard tabbed web browser which mimics Google Chrome. This is how the application looks when you start it. Please see the references section for detailed information about these two components. This application uses CefSharp as the web browser and the Tor.NET library to connect to the Tor network via an HTTP proxy. I've been using CefSharp Chromium browser component in my projects for some time and I changed the WebBrowser in the project with CefSharp and this is how this application came to life. When I read the excellent article "Tor.NET - A managed Tor network library" by Chris Copeland, I started to play with the sample application in the project which uses the Internet Explorer component (WebBrowser). When I hit a web site which I can not access because of a web filter, one of my options is to use the original Tor Browser which is a custom version of Firefox and I can simply say that "I don't like it".
