In the Abrowser web browser, I don´t know why, when playing a YouTube video it plays like the original propietary flash. The only thing I have installed on it are some extensions, but none of them are related with flash players. It´s curious because Ihave understand that Abrowser uses Gnash but... this is not gnash.

It looks like you're using the HTML5 player, not flash.

And can I do the same in Tor? Because it´s free software, right?

It works with the Tor Browser Bundle as long as you allow HTML5 canvas image data extraction (a warning that pops up when a video is about to play).

I prefer to stream videos from youtube and others with gnome-mpv. It's uses less resources and is more stable and reliable than those HTML5 players.

Of course, gnome-mpv doesn't use Tor by default.

Sorry but that is wrong.
It's not necessary to allow that option to use html5 youtube videos. Tor browser works fine when you chose "not now" or "never".

You should NEVER allow that request as it might remove your anonymity.

You're right. Didn't work the first time I tried, but for some reason it works now. Thanks for pointing it out! =)

It is not libre. It's proprietary JavaScript code instead of a Flash object with proprietary ActionScript code. It's just that Abrowser is capable of running JavaScript code, whereas Flash Player is needed for Flash objects.

I would recommend disabling JavaScript and using unofficial tools to watch videos, like ViewTube and UnPlug. As a last resort, youtube-dl is usually the most reliable.

Indeed. https://trisquel.info/en/wiki/play-videos-without-using-flash lists many options that do not require executing proprietary JavaScript.

The only thing I want to do is to play YouTube videos with a free software. Actually I´m using HTML5 everywhere but some videos cannot play

How can I have the compatibility with Media Source Extensions, MSE & H.264 and MSE & WebM VP9? This is in the case of the Tor Browser

Firefox doesn't currently support MSE. But the JavaScript code that takes advantage of MSE support is proprietary, anyway.

So why Abrowser supports it?

Oh, does it? I guess my knowledge is outdated. Maybe MSE support was added between the last LTS and the current version. Or maybe Tor Browser disables the feature for security reasons.

I really recommend turning Gnash of in your browser.

Gnash, long story short, sucks (or at least it did a few years ago and since Trisquel probably hasn't shipped a new version of it (if such a thing exists).....it probably still does on Trisquel).

It does not exist. The last version of Gnash was released in March 2011: https://savannah.gnu.org/news/?group=gnash

In fact, all projects of free Flash player have been abandoned. The last release of swfdec was in 2008, that of Lightspark in 2013 and Mozilla recently announced that Shumway is abandoned.
