YouTube stop working via https after I updated from Firefox 19.0.2 to 20.0.1. But via http it works fine. Also embedded YouTube doesn't work on sites that use src=https:// and works on that use src=http:// ones. Everything working fine as I roll back to 19.0.2 and stop working after re-update. I've tested the Safe Mode — the same effect, doesn't help. I've tested new profile — everything seems fine, YT works via http and https. So, if there's no clear solution to my problem, is there any way to dump full 'about:config'-config to diff with default one?

hello reiser, this issue is likely caused by the following configuration you've performed in about:config: security.mixed_content.block_active_content: True & security.mixed_content.block_display_content: True.

Thank you very much! I'm very glad solution have been found so easily. It seems odd to me this settings had no effect in FF19.
