Doesn't work with Google 2 factor authentication Rated 4 out of 5 stars

Isn't this a plugin? If not, then make one. As for Google talk working in TB chat it doesn't. If I use the application specific password it complains "Error: Received unexpected data" and never gets through.

Nice but doesn't do Skype (Pidgin does) and I have a problem with Google Talk because I'm using two factor authentication and this extension doesn't handle that!

Pidgin doesn't support Skype without a plugin, and Google Talk is completely unrelated to this add-on (and works out of the box in Thunderbird 15+, even if you have two factor authentication).
