View notifications of Google+ activity when signed in, anywhere you go on the web.
See what’s happening on Google+ with the Google+ Notifications extension.
Whenever you have a new notification (for example, when someone adds you to a circle or shares a post with you), the extension button will turn red and show you how many updates are waiting for you. Once you click the button, a window will drop down showing you all of your most recent notifications. You can act on notifications right from the extension, whether you’re replying to a comment or adding someone back to your circles. That way you can stay up-to-speed with your circles on Google+ no matter where you are on the web.
