Hello friends. This is my first post here. I am posting this for an issue with my Firefox browser on Ubuntu 20.04. For a couple of days, I am unable to watch YouTube videos on the Firefox browser. Because, after several attempts, I am unable to open YouTube on Firefox. Guys, I don't understand why this is happening and how to solve the issue. Can you provide any suggestions for this?

What happens when you try?

Did it used to behave differently, or always like this?

Do other web browsers have same problem or is this only firefox?

Do you have any extensions or add-on's applied to firefox? If so, have you tried disabling them?

Welcome to the board!

It seems you aren't the only one getting a problem — Firefox can be difficult. Have a look at these ideas

Try starting Firefox from the command line, then viewing a Youtube video. There may be some useful messages thrown to the terminal.

As an aside, I watch Youtube almost daily on Firefox and have encountered no issues.

Hello. I am not an expert person on this, and this is my second post also. I am posting this mainly for two reasons. One is I have a solution for you. and another one is for me.
Have you tried to disable the Hardware Acceleration on Firefox? If not, then you should do it first. If there is any problem, you can follow this link. Hopefully, you will be benefited.
Guys, I want to use Windows and Linux on a single PC. Can you tell me how to possible it? If any solution, please provide me.

None of the ideas mentioned are specific to Firefox - they're just good general browser troubleshooting recommendations, essentially what post #2 already requested.

No, I would say: YouTube can be difficult.

Hi,

You could try to reinstall Firefox:

You could also try another browser like Brave or Google Chrome

I run an independent firefox.

If interested, YT works for me. I have OpenH264 Video Codec and Widevine

gives me a score 512/555

If interested you would download your lang from here
https://www.mozilla.org/en-GB/firefo...esktop-release

unpack it to your home dir.

my desktop icon file is using a sym link from
/home/name/firefox/firefox to /usr/local/bin/firefox and contents

[Desktop Entry]
Type=Application
Name=firefox
Exec=/usr/local/bin/firefox
Icon=/home/name/firefox/browser/chrome/icons/default/default48.png
Terminal=false
Categories=Application;

change name to your login name please

Or, dont use your home dir at all....
untar it to /opt then
But anyways I dont think OP was looking for install instructions.... and that desktop file lacks the actions like new window etc t... if debian you can just copy the firefox-esr.desktop and take out the -esr parts and then get all the languages and actions easily...
