Google has launched a new version of Google Toolbar for IE that includes a Google +1 button and a Google+ Notifications button.

These buttons allow users to +1 any webpage and share it with their circles on Google+ as well as check their Google+ notifications while they browse the web. These new features are only supported in Google Toolbar for IE8 and IE9.

Google Toolbar 7.2 for IE is available for download in English only today and will be available in other supported languages soon.
