Vivaldi browser uses the Pepper version of Flash (PPAPI) that Chromium or Chrome uses. If you are noticing a “Couldn’t load plugin” or “You need to have the Adobe Flash Player to view this content” message in these browsers when you tried to view flash-content on web pages, then you have to install Pepper Flash, follow the below instructions to install Flash player in Vivaldi browser.

Windows and Mac Users

Linux users

We now look in the install location used by the Official Flash package provided in the Canonical partner repositories on Ubuntu Linux. In addition, if you have Chrome installed we can also use their copy of Flash. Vivaldi smartly determines which is the most recent version if both are available.

Ubuntu Linux

If you are an Ubuntu user, you can issue the following commands in a terminal window to enable the Ubuntu partner repository and install the Official Adobe Flash package:

sudo add-apt-repository "deb `lsb_release -cs` partner"
sudo apt update
sudo apt install adobe-flashplugin

Restart Vivaldi and you should now have a working copy of Flash.

Other Linux distributions

Refer to your distro’s documentation and install the package that provides Pepper/PPAPI Flash. If Flash still does not play after installing the Pepper Flash package, comment below with the Pepper Flash install location (if you know it) and the name and version of your Linux distro.

You can also use this script if your distro does not provide a Pepper Flash package.
