Currently, the Open Browser keyword requires users to pass a URL to navigate to upon opening the browser. However, in some cases that may not be desired and the user might simply want to open the browser. (as in the case of Chromium-based applications).

Users should not need to specify this argument and the URL should be None by default. If None or not specified, navigation shouldn't occur.

I don't have a PR for this yet but can have one as soon as I can get back to my computer. Also sorry about the title "pay" - autocorrect :)
