lingQ status buttons disappeared In Firefox

The flash cards keep disappearing in Firefox.

Hi sgarner2,

Thank you for letting us know. We’ll fix this bug asap! In the meantime please use Chrome or Safari.

It happens in chrome too. I think it is related to wrong javascript/css.
Also - If you need to push button
1 2 3 4 X V
Move your pointer from right to left then
V will disappear first, then X and so on. And stop your pointer on a button that you want to push and push it - don’t move your mouse since your mouse on it , or it will disappear.

This bug has been fixed! Thanks for your patience.
