How can you automate Firefox from C# application?

Question

Start with the simplest task of capturing the URL in Firefox from a C# application. It appears using user32.dll Windows API functions will not work as is the approach for capturing the URL within IE.

Answer 1

You can use Selenium WebDriver for C #.

This is a cross-platform API that allows you to control various browsers using APIs for Java, C#, among others.

Attachment of a code C # with Selenium WebDriver tests.

Answer 2

Should I need to do a capture of the URL with AutoHotkey, for example, I would send Ctrl+L (put focus in address bar and highlight content) and Ctrl+C (copy selection to clipboard). Then you just read the clipboard to get the info.

For more complex tasks, I would use Greasemonkey or iMacros extensions, perhaps triggered by similar keyboard shortcuts.

Answer 3

WatiN has support for Firefox.

Answer 4

WebAii can automate FireFox, including setting and retrieving the URL
