"Best in Performance, This addon does NOT track user activities same as others". That may be, and without doubt it's easy to use, yet I feel I don't have enough control. i.e. I don't see right away which URL(s) exactly will be allowed when whitelisting a domain and I don't see which URLs might possibly require whitelisting, too.
PS: You're right, you do deserve 5 stars - my problem is my problem ;-). The request blocker is enabled but my point is that I don't see, which URLs/requests are being blocked without going into options. Thus I can't "quickly" decide which ones to enable or diable. But I see that this Addon is just perfect for the average web user! You've earned the fifth star solely by this great and instant support.
