I suspect it's his browser or an extension he's using with it. It looks *really close* to Firefox, but not quite.
I even took HIS screen shot, cropped to just the tool bar, and tried to use google image search to figure out what it was
No dice though...
My day to day browser is Opera, which I find great for just about everything, and it seems they're ahead of FF in useful developments (things like the 'speed-dial' (or what ever it is called) front page).
However many financial sites come with added layers of security and only function correctly on IE or FF, so all such sites I use are now configured into the front page speed-dial of FF (v10.0.2).
The long and short of it is I checked Google via FF, and indeed the search by Image function is there. So thanks all, we got that resolved, and I know where to find it in future!
