When Raptor is run with Google Chrome, Chrome starts up,

A lot seem to have been changed since this bug was filed...

a) not as the foreground app, but as a background app behind the terminal,
at least for me on OSX, and

Chrome no longer opens as background application, but appears as front-most application above the terminal.

b) starts up with "chrome://welcome/?variant=everywhere" as the default tab,
ideally it would be best to start it up with a blank tab to ensure that
there is no background work going on during the raptor test run.

It's starting with a blank tab nowadays.

Also, we may want to have the default Firefox tab on startup be
'about:blank' instead of the standard new tab. The standard new tab has
'highlights' and 'top sites' - although they're blank since it's a clean
profile, so it's probably not a big issue.

Given that we are switching to browsertime and with this tool we have a blank tab, I assume this is nothing we should spend time on.
