BuddyFox adds instant messaging support for Mozilla Firefox
BuddyFox is a recently launched instant messaging app for the Mozilla Firefox web browser.
It runs from within the Firefox web browser and come handy for users who spend most of the time in it.
The bad thing is that it requires you to create an account with the service itself. It does not support third party protocols.
Personally, we think that we already have too many instant messaging protocols around. Creating another one that is used by one Firefox extension alone is not worth it. You can always use something like Meebo.
