In bug 255962 I wrote a patch to allow passing to the minibrowser extra parameters via some extra arguments In turns out that passing extra parameters was already possible, but I couldn't figure how to do it. So I think it is a good idea we document this. My proposal is to show this on the help of the script, which currently is hidden and shows the help of the minibrowser binary instead.
