If you've ever looked under the hood in the about:config section and wished there was a faster way of seeing what each preference did, this is for you. All three of you. It will open up a new tab in Google using foreground or background focus preference (whatever you have set up) via right click context menu and will give you an idea of what each preference is. Google is hardcoded in now because it has the most results for these names. I do not currently plan to implement multiple sources.
