I am trying to disable a button I made for a game. When I open the game in all the other browsers, the button is disabled. But, when I open the game in Firefox, the button is not disabled. If I switch the input type to "button", the button disables. Here is the code:
<input type="image" src="mapIcon.png" alt="mapIcon" class="mapIcon" id="mapIcon" onclick="openMap()" disabled>
