@whitetapeti: Update the Ublock filters

@asteen: You may want to look at your filters and/or trusted sites then, you may not have something enabled or you could have something marked as trusted

@whitetapeti: It is probably the Opera adblock that's causing the problem as my Ublock Origin isn't being detected by YouTube. If not then update Ublock Origin.

@vytoking: Make sure that you also have the built in Opera ad blocker disabled
