Uninstalled Adobe Flash in Firefox

[Han Solo1]

I now have problems playing youtube videos because I uninstalled flash. I am now having problems reinstalling flash.

YouTube should work fine without Flash, as it defaults to HTML5 video (since 2015). I.e. there might be a different issue with your setup.

Actually I am getting "Your browser does not currently recognize any of the video formats available". I have installed "YouTube use flash player 0.1.2" on firefox which helps to play the video. But it wasn't like that before. I have installed Adobe Flash Player 28 NPAPI and Adobe Flash Player 28 PPAPI.

I don't think html5/H.264 works in Windows XP unless you're using an old version of Chrome

I have installed Adobe Flash Player 28 NPAPI and Adobe Flash Player 28 PPAPI.

Firefox uses the NPAPI version. The PPAPI version is for different browsers (Opera, Chromium-based apps).

Could it be that you have add-ons/plug-ins/extensions that may interfere with the video interpretation? Try watching a YT video with as much as possible customization disabled, see if that changes anything. That may help finding the offending “helper” tool.

try clearing your internet browser cookies, restart firefox then retry youtube.

I get this message on some YouTube videos.

The cause? XP.

Many sites, including YouTube, no longer fully support Windows XP. If you are running that O/S, then that's your problem.

There is a workaround that works about 75% of the time. If you get the message, right click on the video screen and click on "Copy Embed Code." Paste that into Notepad and edit it so it becomes a valid URL. For instance, this is the normal link to one of my YouTube videos:

https://www.youtube.com/watch?v=qDNjouEByTo

Here is the "embed" code, just as it was copied from the right-click & copy operation:

<iframe width="854" height="480" src="https://www.youtube.com/embed/qDNjouEByTo" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>

and finally, here is the URL that I put into the address bar of my browser that will play the video without the error message (most of the time):

https://www.youtube.com/embed/qDNjouEByTo

So, I don't think the problem is simply the act of uninstalling Flash.

BTW, if you are still not able to re-install flash, make sure you are using this link:

Download Adobe Flash

Make sure to uncheck the installation boxes for McAfee and any other garbage software that is listed.

His computer details don't say "XP" but I 100% agree.....YouTube and XP no longer play nice together.
I only have problems with NEW videos. If you wait a few hours YouTube will generate something that XP users can play.

It seems uninstalling Java first and then uninstalling/reinstallinf Flash did the trick. For some reason clicking the get adobe download link redirected me to a java script link so I decided to uninstall Java.

I’m glad you got it working. But Java and JavaScript are unrelated (except for the name), and Java is not invoked with HTML links or YouTube or Flash installers. (There are good security reasons to not view Java content in web browsers, so uninstalling might be a good decision anyway.)
