YouTube is working fine, but some other websites show an error about missing Adobe Flash Player. How can I get rid of this and verify that Adobe Flash Player installed properly?

I am using Ubuntu 16.04.

    YouTube can use HTML5 video, so that doesn't actually say anything about flash. How did you install it, and what browser are you using? – zondo Apr 5 '17 at 13:02
  • An up-to-date summary of Flash on Ubuntu is available at this page. – Gunnar Hjalmarsson Apr 5 '17 at 14:08
  • Hi zondo, I am using firefox and vivaldi browser. – RjV Apr 6 '17 at 11:08

For verification you can use Adobe official page: https://www.adobe.com/software/flash/about/

Or unofficial: http://flashbuilder.eu/flash-player-version.html

Seems that you don't have Flash player installed. I recommend to do an easy install and install all "restricted" software packages, including FP. Open terminal and execute:

sudo apt-get install ubuntu-restricted-extras

Since you are using both Firefox and Vivaldi, you should install the adobe-flashplugin package from Canonical Partner. It provides Flash for both those browsers.


Visit the plug-in overview page of your web browser and look for Flash Player. For Firefox that is about:plugins; Chromium and Chrome accept the same but will redirect it to chrome://plugins.

Watch out for the possibility that your web browser may be configured to disregard and disable plug-ins globally in which case they may show an empty plug-in listing even though Flash Player was installed successfully.
