If I access the livemap via SSL link https://project-gc.com/Tools/LiveMap
the menu icons on the left (filter, settings, info, menu) are invisible.
Accessing the livemap via HTTP as http://project-gc.com/Tools/LiveMap
the icons are shown.
Okay, I could always use the HTTP link, but at least the greasemonkey browser extension always links to the HTTPS page.
Tested this with Firefox on Linux and Windows.
