I can't find the Vkings: War of Clans button on firefox. (I'm having loading problems and it's really annoying to have to throttle my internet because why on earth should I have to do that???????)

I use firefox  so it is  both  findable and useable there.

Also can't see how it is anything to do with having too fast an internet speed, and if it is that, why not slow yours down  if that solves the issue?
