From Firefox 57, the previously used native interface (XUL) has been omitted, this caused a complete reprogramming with the new interface WebExtension of Firefox. This interface does not yet contain all previous functions. That's why unfortunately many details had to be changed.

The previously used two-part switch with a one-click handling was possible, unfortunately no longer exists. That's why two clicks are needed now.

The default theme has been changed from a light to a dark background. With a dark background, the MM3-Icon (button) is not clearly visible. This has been changed in the new version.
