Whether you’re soaking up the sun at Adventure Island or braving thrill rides at Busch Gardens, these secure charging stations allow you to charge your cell phone while enjoying your day.
Make sure to head to the park's official blog to see some photos of these new charging stations.
Anon- I think it might be one of your extensions in firefox acting up. Go to your tools>add-ons and look through your extensions and see if there's one there you don't recognize and disable or remove it. I use firefox daily and am having no issues with OTPN. No pop ups or redirects, but have had an issue with another site in the past that sneakily activated an extension while I was installing something else.
