Good idea in theory but doesn't work in concept. Every relevant webpage element I wanted to hide could not be hid properly with this addon. In the best case scenario a simple refresh will restore what's hidden - in other cases, the element was automatically restored. I haven't found any instance where the removal was "permanent".
If this addon could create rules for things like forums with multiple similar pages, or even if it actually did what it says it does, it would be a pretty useful addon.
