No Placemarks Displayed

I have been able to get the plugin to work as a module (incontent)
and as a plugin in an article, but the map will not display as a
menu link.

In all cases, the placemarks do not display. I have only 1 category
and group for the placemarks.

I have Joomla 2.5.6 and latest plugin.

Any suggestions to get placemarks to display?

Hi.

Do you get map, or you still have troubles?

I did post and update noting that I could see the placemarks with
Chrome and IE, but they still do not show up with Firefox.
ABout 25% of my viewers used Firefox, so it is stil a problem.

Can you give me direct link to your page
and Explain what you expect and what you get
