"I suggest you first reset your browser’s profile as it will most likely resolve the issue with BBC’s HTML5 player.
You could then proceed and try uBlock Origin instead of the built-in ad blocker to see if it resolves the other problems.
As for the website you have linked, it appears the same in the other Chromium browsers I have tried whereas it does not load any content from Chrome which makes it very likely for it to be a problem with the site itself."
I have the same problem- located in Canada - what does "reset the browser's profile " mean? I am not a techie. I just want this to work . Works fine in current version of Chrome - I follow the instructions , on Opera's site no less, to go to Adobe and install - nothing happens. I try to find Flash plugin in Opera to configure -doesn't show up. Like the browser but this is simply a non-starter and I will return to Chrome . I have wasted to much time on this already.
