[Plugin: WP-PostRatings] Does it work in Firefox?

Hi guys,

Does the plugin work in Firefox?
It does not allow me to click on icons when I open a web site in Firefox (meanwhile it allows clicking in Chrome and IE).

Example:
Here I have the stars displayed at the bottom of the post, but they are not clickable in FF:
