Not opening on Android>Firefox browsers

Hi there,

First of all thank you for the plugin it’s great and saved me a lot of time creating my own collapsing plugin 😉

I have though a problem regarding Android devices. On my Android device if I visit my site with the Firefox browser and touch the tab it collapses for some milliseconds and goes immediately back down, resulting in a flickery-like behavior. The site is http://www.alpenhirt.ch .
I only can find this behavior on Android>Firefox browsers. On the same device with the Chrome browser it works like charm! On every other Computer, Laptop, Tablet it works also fine. I have no idea where to begin looking for the problem and I hope you can help me 🙂 I hope you have an Android smartphone to test it 🙂

Best regards
Muhamed
