Various times during surfing when I want to use Hover Zoom and it doesn't work I look at the extensions and they're gone! So I go to the Chrome Store, add Hover Zoom and with it come the other extensions. I have only 5 extensions: Logitech Smooth Scrolling for my Logitech keyboard and trackball Ebates Bring Google View Image Back uBlock Plus Adblocker Hover Zoom. Today, the 14th, the 3 dots are back so I don't know what happened behind the scenes. Anyway, I was happy to find the menu and went on my business. When I clicked on the circle the menu dropped down but nowhere was an update included. When I put the cursor on it, it said 'Customize and control Google Chrome' and mentioning a Chrome update.

I added my reply to my post yesterday saying that someone mentioned an orange circle with an exclamation mark (I think) in place of the 3 vertical dots and, sure enough, I had that circle.
