Rated 3 out of 5 stars
First off, if you have problems with this version, get the one on the developer's website.
Not bad. I'd like to see more features, though. Like the ability to pick which friends' status updates I want, so I don't have to turn that feature off.
More importantly, this needs to integrate with Chat, and eventually all other Facebook-developed apps. (Maybe even add a plugin system to handle third-party apps)
I didn't have any problems using this in Linux. Except that the popups need a little extra whitespace on the bottom.
