Just like you stated it has something to do with adblocking. I use Operas internal one. I was fiddling around with it and discovered that the tracer-thingy is the culprit. Doesn't matter if the adblocking part is on or off but if I turn off the "tracerblocker" it works as it supposed to. Thanks!
Been using different kind of blockers on several browser through the years but this is actually the first time any of them has given me any problem. At least of this "magnitude" in lack of better term. Anyhow, thanks for the help!
