In the past I've been able to block youtube videos with a simple add on from firefox, now it seems I can't! I've even reinstalled an older version of firefox and that did for a while, until firefox updated on auto. Research suggests hacking into firefox could be an answer, So I went to Chrome and couldn't block them there. I don't want the credit on my dongle to be eating away, help what can I do?
'Block YouTube et all', but I do want to download certain videos, but not others and this is where it eats into my credit. This 'problem' started a few months ago, so I just change the downloader and flash blocker until they worked, expecting a solution to be made. But it appears that youtube aren't allowing them to work in the old way, it was 'fine' before I did a complete reinstall so I've possibly altered something, some how, if so WHAT?
I'm on Firefox version 38.0.1 and can still block flash player. It could be the HTML5 player that's causing you problems. There's a thread on disabling the HTML5 player here, superuser forum that might help.
