The GrandCentral Click to Call Firefox extension calls phone numbers on web pages using your GrandCentral account with the click of your mouse. That means whenever a web page loads, the extension recognizes phone numbers on the page and turns them into clickable links. Clicking the number will call the phones you’ve connected with GrandCentral, and when you answer, GrandCentral connects you to the number you’ve clicked on.

Features are -

1. Automatic login to your GrandCentral account
2. Hover your GC number on the toolbar for the most recent call
3. Double click your GC number to redial the last call
4. Quickly access your voice messages, address book, and call log by right clicking the toolbar
5. Click any phone number to place a call

New message notifications and new missed call notifications might make it into the future release.
