I've been having a strange problem ever since an update from several days ago.
Embedded videos do not play on some sites.
Especially Youtube videos, but also others. Strangely, embedded vids on facebook do play, but on other sites they don't and I need to open the video on youtube.
I am using Ububtu 12.04 lts and Firefox for a browser. On chromium it works fine
Has anyone else encountered this problem?
