Rated 2 out of 5 stars
If you're OFFENDED by MySpace, this extension will keep you from going there, and will give you a big pat on the back for doing the "right thing".
It won't protect you from malware hosted on MySpace. I don't think this is a bug because the developer and users show no interest in this kind of security.
Ratings are supposed to be for how well you think an extension works (or doesn't work), not about your opinion of the concept of what it does... (from another comment)
If this would be applied to those who seem to think blocking MySpace is the greatest thing since fire, the comments would be much more helpful to someone trying to decide if this plugin does something useful for them or not.
Does it work as well as putting MySpace in your hosts file, or blocking it at your router? I don't know - I'm not going to test MySpace THAT thoroughly for malware. Does it block XSS references to MySpace from other sites? Does it allow you to extract needed information from the MySpace site without being exposed to whatever is so dangerous?
As far as improvements, the two major ones are 1. DEFINE YOUR GOALS (does the one-sentence summary on the plugin page define the spec completely?), and 2. MAKE IT UNIVERSAL. Others dislike AOL, Yahoo, CNN, Fox, M$, the RBN, et.al as much or more than MySpace (I mean really - can someone point me to what is so bothersome about MySpace BESIDES malware?)
