[CLIENT] Continuously losing connection in champ select when internet is open.

This problem recently started occurring once the new champ select was put in. Any time I have a web page open in the background (even if opened before champ select), or open one while in champ select, I lose connection to the server, and get kicked. It is rather frustrating because I lose LP and I am scared of being put in low priority queue etc/ban. Also I haven't heard of anybody else having these problems. I use Firefox FYI if that might help. Thanks.
