The (old) Roof Azimuth Tool doesn’t work when I click the button

On some versions of the Firefox web browser, clicking on the button to put your mouse pointer into “measure mode” does not cause the button to stay green and activate measure mode. Try clicking and dragging the button a short distance and then dropping it to workaround this issue. It is also possible to use another browser to view the page and run the Roof Azimuth Tool.
