That would be an option of the player if it has it. However, the player could not play the clip any faster than its data is received.

You could always download the clip and do this on your system.

there is no desire in each video to press the same settings , I want unification. In some sites there is no button choice speeds, the speed the Internet not worries, worries the speed replication, I want 1.5* or 2.0*.

download to PC 1 minute ..12 minute video a very time-consuming too (too lazy).

I want to change playback settings globally and permanently

Hello askmix,

What may be the ideal playback speed for you, might not be what others want - therefore there can't be a default setting.

Would you please take a look at this article, and scroll down to the section :

Accelerate or reduce the playback rate

Maybe you'd like to try an extension that will do what you want, like :

https://addons.mozilla.org/en-US/firefox/addon/videospeed/

Or :

https://addons.mozilla.org/en-US/firefox/addon/playback-speed/

thanks, https://addons.mozilla.org/en-US/firefox/addon/videospeed/ working. DECIDED.
