I've researched this to some extent already by searching StackOverflow and SQA, but cannot find the answer.
Is it possible to open a new WebDriver browser window from the current FirefoxDriver (IWebDriver) instance, or do I need to instantiate a new FirefoxDriver instance? It would be nice to open a new tab, but I read that this is not possible with WebDriver.
The [hidden] part of my question .. bonus if you know, but not required. :-)
And also, I don't even need to see this browser window, so I'd prefer that it's hidden. Does the browser need to be seen or can I do the webdriver tests without having the task/browser open in Windows?
