Really like the simplicity of this add-on, however the current behavior of Google Maps does not center a place marker on the screen so the coordinates are inaccurate when a specific place is selected but the marker is not precisely centered manually.

This addon does what it promises and is very helpful, but it breaks certain websites, particularly the button layouts.

EDIT: I could not find your mail address in the developer profile to send screenshots of the issue. Try the website mydealz.de and look at the top bar buttons.
