Invite your friends! Rated 5 out of 5 stars
This add on works very well. Sometimes, the comments take a moment to load, but overall, the performance and functionality are exceptional. The idea behind it is something that the internet has needed to implement for a long time. Finally, it is here.
The developer involvement behind this extension is incredible, much more so than the majority of extensions available for firefox.
The ONLY thing wrong with this extension is the lack of a community backing. Once this is obtained, the sky is the limit.
