For some reason on this page: http://deadislandwiki.com/wiki/Template:Moresby_map '''FIREFOX: ''' The image icons (red fire hydrants) do not display a pop up box when you mouse over them. As a follow up to my message, and to help clarify, here are some images: Firefox (no pop up appears): http://gyazo.com/3cdf2296ce1d1eee9eca0f2201855e52.png ''' Internet explorer 7.0 to 9.0''': these pop up boxes DO appear. Internet Explorer (pop up appears): http://gyazo.com/3f2017f926d006f82a34c8db8c60c634.png This problem happened before in a similar situation and I solved it by simply removing a space in the coding. This time I cannot find out what the problem is. I guess firefox is more sensitive to incorrectly placed space characters? I have attempted to use the firebug extension in the past and was never able to get it to work. If you could point me in the right direction on why this maybe happening I would be most grateful.
