HELP! i cant see the teemo link

Am i missing a plugin or something? i click on the link in the client to check it out and i see the skull load, but then the webpage goes black after it finishes loading. Also, if i try to click on a picture to enlarge it through the league forums it doesn't appear. i just get the hide icon that i cant click on and instead i have to right click and open in new tab. (my browser is firefox)
