I use Google Voice and I don't see any plug-in for GV, what would you gain from it? To bring up Google Voice, I have a bookmark on bookmarks toolbar : '''name:''' GV : '''Location:''' https://www.google.com/voice#contacts/Google+Voice : '''Keyword:''' GV: : '''Description:''' Google Voice available in US can call US and Canada for free. This bookmark opens your Google Voice input box.
