With the release of Firefox 23.0.1, different options were changed and I had to go back in to change them. One small change was disabling the start of videos on Youtube, Dailymotion, etc. The plugins.click_to_play was set to true, and changing it back to true today, videos are still automatically playing on their respective website. Is there any alternative or adjustment in the options that will do the same as plugins.click_to_play? Prefer this option to work, but if there is something else out there, I'll consider it.
