So far, I've tried this on multiple games on multiple sites, but it seems that on Firefox, the wasd keys don't work. However, other keys, like inventory or other buttons, still function. The games work fine on Chrome.
@hagamablabla Did you try updating your flash player? And also, laptop keyboards do have drivers, so you should check out updating them.
A little out of topic, but I think if you use a trackpad and keys at the same time, one of them might not work. It was an issue I had with my old laptop.
