As Chrome continues to develop — or, rather, as Google continues to tweak it — it is more and more likely that you may find features that you weren’t aware of or suddenly be confronted by an icon that means absolutely nothing to you. This happened to me recently when I noticed an icon that resembled a pair of twinned diamonds to the left of the bookmark star in my address bar.
I hovered my cursor over the triangles to find out what they were and was greeted with the phrase “page wants to install a service handler.”
Thanks. Clear as mud. What is a service handler, and should I let the page install it?
