Scenario is simple:
If you add a web browser in visual studio it adds IE. If you are logged somewhere with IE it keeps you authenticated like reading cookies or sessions. Web browser component and IE is the same.
So, is there a way to access firefox from c# (like web browser or some way) and lets say load a page and get the html of this page? Or load a page, fill a textbox and click a button, all these via c#?
Selenium is a browser automation framework that will let you perform these tasks using C#. There’s a driver for Firefox that works very well.
