This seems to be similar to #4141, but since Robert reports it also happens with 1.12.1 and that no error is displayed in the console that doesn't make sense. Perhaps our Flash YouTube blocking solution just doesn't work 100% of the time?

Robert has noticed there are actually exceptions being displayed, I've updated the issue. Certainly doesn't look like a recent regression in any case.

Robert please can you confirm this change fixes the problem? Since I couldn't easily reproduce the problem and the fix was so obvious I took the unusual step of pushing a fix anyway. If the problem remains for you we'll have to revert this.

Issue no longer occurs on / OS 10.8 / Safari 6 / Easylist.

I have ADP 1.12.4, Safari 11.1 and Sierra 10.12.6. ADP does not block any adds in YouTube. If anything it's worse. Is there a fix yet? Thanks.
