Update: I found a better browser so I am no longer supporting this add-on.
I recommend the official Google Voice extension instead.
Google Voice is a popular telecommunications service from Google that gives you one number for all your phones.
This Firefox addon makes it so you can click-to-call numbers on any website using your Google Voice number and send text messages without leaving your browser.
There is no Google Voice API for development, but everything including SMS and recorded voice messages can be received via JSON and XML requests.

Unable to place call to XXX-XXX-XXXX
Problem: You entered your Google Voice number as the forwarding number, or
Problem: You entered a number that is not on you Google Voice account as the forwarding number
Solution: Enter one of the numbers set up on your Google Voice account
The addon does not detect numbers on “…..”
Problem: The page you are viewing contains frames, or
Problem: The number you are trying to click is loaded via AJAX after the add-on scans for numbers
Solution: If the content was loaded dynamically you can detect new numbers by double clicking the GV icon in the status bar. If the page contains frames (such as Google Contacts) there is nothing you can do at this time.
The addon does not work in Flock
Problem: You are using Flock
Solution: This is the Google Voice Add-on for Firefox. Download Firefox or try the official Google Voice extension for Chrome.
I do not see the addon in the toolbar
Problem: You are looking in the wrong place
Solution: Make sure your status bar is not hidden because that’s where the Google Voice Add-on for Firefox is located.
