VIMEO Movie doesn't play in SM

[Ztruker]

This movie: https://vimeo.com/159690401 won't play in Seamonkey. Plays okay with IE 11.

Doesn't play will Add-ons disabled either (SM Safe Mode).

I have SM 2.40 installed but the UA string doesn't seem to show that. I use Prefbar and made sure the User Agent string is set to Real UA.

That seems to require Flash. Do you have the latest version of that Adobe program installed? http://kb.mozillazine.org/Flash

[Ztruker]

The latest version was installed but I had it set to "Ask to activate". I did this awhile ago to prevent movies running in the background and it worked but caused other problems, like this one.

Set to Always activate and that site works okay now.

Thanks for getting me pointed in the right direction.

You're welcome.

What a video! THANKS FOR THAT LINK!

[Ztruker]

You're welcome.

Not working for me again, sigh. I have latest Flash and it's set to Always activate but it's not working.
I even tried turning off Protected mode and that doesn't help.

Anyone have any ideas?

Time will cure this. Works fine in 2.43 under Windows 7 x64 (local build). No flash just html5.

At first, it wouldn't play for me in SM 2.43 (akalla) even in safe mode, but played fine as HTML5 in Fx 45.1 ESR. I found that re-enabling media autoplay, which I had disabled, fixed the problem in SM.

(In about:config, set media.autoplay.enabled to true)

Not working still/again.

Trying to play this Vimeo movie: Eagles at the Conowingo Dam, all I get is a black screen.

Works in IE, Edge and Firefox.

There is no media.autoplay.enabled in about:config. Should I add one?

[Ztruker]

I should try things before posting. I added media.autoplay.enabled and set it to true and now the Vimeo movie plays okay. Thanks SportsFan.

Glad it helped, Ztruker.
