Firefox 37 defaults to HTML5 video! I want Flash back by default! How do I do this?
I use Flash Player everywhere (because it has acceleration etc.) and Firefox has switched all video to HTML5.
How can I get my system working like it was before? Before the update?
I can't use a Firefox addon to force Flash because it breaks Greasemonkey scripts and other plugins?
Please advise.
Seriously Mozilla, please make this information available at least on the release notes BEFORE making major changes. Now I must waste my time to get Firefox working properly again. Microsoft does things like this.

You would have to click the button on the YouTube HTML5 checking page to switch to a Flash based player.
That article is about using a special feature that allows a website to check what media types a browser supports for the HTML5 media player via canPlayType.

You need to change your Firefox Configuration. Please do the following steps :
- In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
- Click I'll be careful, I promise! to continue to the about:config page.
Then, set media.webm.enabled, media.ogg.enabled, media.windows-media-foundation.enabled and media.wave.enabled to false by double-click and restart Firefox.
Hi,
For the YouTube videos you can configure it by https://www.youtube.com/html5
Unfortunately I don't know how to configure Firefox. See this question: https://support.mozilla.org/en-US/questions/1044212

Hi iNef. Tried disabling all those (setting to false) and YouTube still uses HTML5 video player. I even disabled "media.mediasource" and same story, still doesn't work.
HTML5 forced. Thanks for trying to help.

Hi. Going to that YouTube link doesn't help. Also, that other article did not help. Read the entire page.
Firefox 36 didn't have these problems, Firefox 37 does. Something has been added that's causing this. You can't disable HTML5 video it seems.

Hi cor-el. Not sure what I'm looking for on that document?
Firefox 36 YouTube plays with Flash. Firefox 37 YouTube uses HTML5 Video Player. Not sure what it's doing this. I believe "media source extensions" is new in 37, but disabling it still doesn't allow Flash to be used. I disabled most of the media settings (for wave, ogg, etc.) but still uses HTML5 video player.

Okay, so I thought to try again, so I updated to the latest 37.0.1, and the problem is gone. Flash is back. Didn't have to disable anything or make any changes on YouTube.
Thanks guys. :)
