Bug, after rightclick on any website and click on "block element", a red warning mouse-icon appears first instead of directly the "selection" icon that is expected to appear, with red boxes moving when moving mouse. (first, with red warning icon, no red box moves. This is a very very counterintuitive user-experience)

This is the single best add-on for Firefox and the first thing that I install on any computer (after installing Firefox).

Immer dabei

There was no way for me to whitelist sites on my own! There were no "save" features once I entered the sites.
SO disappointed.
