Youtube Stops after 20 minutes

Hello. Why does YouTube keep breaking something? Until recently it was walking, later turned off the options of the YoutubeflashVideoPlayer plugin because the videos were playing in htlm5 and it was no longer smooth, e.g. volume activating with the arrows in the keyboard worked with a delay, the movie stopped after 20 minutes and the circle was spinning endlessly I didn't have it with flash. Today I go in and see that the page with the film is not loading at all and not just in one video. On Android, it works normally, except that half of the videos have no picture again, it's all black but the sound goes by. I would prefer to give up YouTube, but there is no other. I understand that technology is moving forward every day, but they could leave the older version and the current version so that everyone can switch to whatever they want. Or are there any browser plugins that keep older youtube?

My equipment:
- Intel Core2Duo CPU E4400 @ 2.00 GHz, 2.0GB RAM, ATI RADEON XPRESS 200 series
-Windows Xp
-Mozilla Firefox (chrome browser & opera muuli mi)

Keeps the order on your computer as well as in the browser, I immediately remove all unnecessary garbage (I am a light pedant when it comes to PCs), Mozilla add-ons only uBlock and youtubeflashvideoplayer which no longer works.

Youtube does not break, I'm afraid it is thanks to Windows XP and browsers that are no longer supported on this system. This system was released 16 years ago and unfortunately it's time to say goodbye. Of course, it can be used e.g. in offices, but for multimedia or the Internet it is already a dinosaur.

At the beginning I had win 7 on this computer, it walked well, but the Internet was muddy, and on XP net and computer it works well.

Are there any plugins that play youtube in the old version?

There is no, you can optionally download movies to disk and play from the disk, maybe then they will play correctly.

The disk normally plays, those downloaded from you tube and usually movies from torents, e.g. YouTube snouts, other online players usually work normally.

Don't you have something set up in energy management?
I set it so that working on batteries I have limited performance and youtube cuts out but after connecting the power supply the system goes to maximum performance and playback becomes smooth.

But I have a desktop della, I don't have any separate power supply, it's rather YouTube and Windows.

Or a dirty heat sink on the processor.

No, because since YouTube changed its appearance to a newer one and the flash stopped working it is happening, it plays in other players, they could leave an older version and a new one to choose from, but as usual they have to cut,

Click on YT on the icon of your profile in the upper right corner and select from the menu at the bottom: "Restore Youtube classic look".

The look has changed, but HTML5 is still there.

You won't change HTML5.

I have on one of the computers XP, 1GB of RAM, E2140 and YT work normally, so it's rather a matter of your computer / system / internet / settings.

here the most important thing is that on html5 the movie stops after 20 minutes, without this error I would still give some advice, what settings may be responsible for it? , on the older computer I had the same thing, only YoutubeFlashVideoPlayer helped.

I also stop after about 20 minutes, probably it has to do with inactivity, in the newer version of YT a message is displayed. Just jump forward 5s and continue playing.

The same as here: https://support.mozilla.org/en/questions/1126635 it is possible that something is broken.
If I have time, I will check if it stops under Chrome etc.

From what I see, you can also try to uninstall Flash and see if something has changed.

Is hardware acceleration on or off?

For me, there is nothing to skip, I need to refresh the page, It makes no sense this "inactivity" just a difficulty, I take longer films / vlogs mainly for sleeping to listen to myself, and now I have to get up specifically, after 20 minutes to refresh the page I am not I want to, and I don't fall asleep after 10 minutes, like most only after 2 hours sometimes less . I chrome will not install or opera anyway because I have a musle on the computer, mozilla I mean best here. As for hardware acceleration I can not check on html5 choking on the screen of the PPM player I do not see such an option there, and in the flash there was this option. Uninstalling flash nothing it did not work, even the whole browser was reinstalled with the profile and lime.

Nothing turned off acceleration, I'm just after the tests, the movie after 23 minutes the picture stopped, the sound went on and the circle was spinning, when I rewound the movie it started to work normally again, but it doesn't go with the goal. I don't understand why it's always the same one hundred times happens.
