Text bubbles not displaying full-width in Firefox

[Sam]

Hi,

I've used WPGmappity on a website, and for the most part, it's working great. There seems to be an issue with the popup text bubbles, however: Some of them look fine, but some are much narrower and are forcing a scroll bar. You can see an example of both in the images above.

Here are the links to the actual pages: http://jcsburgerhouse.com/addison/, http://jcsburgerhouse.com/frisco/

I haven't made any customizations to the code, so I'm not sure why this would be happening. Please advise when you have a moment.

Thanks,
Sam

Just wondering if anyone has any ideas on how to resolve this issue. : )
