Using Pipelight worked beautifully for me. It only runs in Firefox, though.

Installing Pipelight

Open up the old terminal (Ctrl+Alt+T) and copy and paste the following commands. To paste into the terminal do Ctrl+Shift+V.

sudo add-apt-repository ppa:pipelight/stable

After adding the PPA, update the sources with

sudo apt-get update

Next, you have to install Pipelight.

sudo apt-get install --install-recommends pipelight-multi

Then, run the below command to update the plugin.

sudo pipelight-plugin --update

Configuring Pipelight

You may have to remove adobe-flashplugin, but I personally did not need to due to it not being installed.

sudo apt-get remove adobe-flashplugin

Then enable all of the necessary plugins

sudo pipelight-plugin --enable flash

Go one-by-one to ensure you're accepting each's license agreement

sudo pipelight-plugin --enable widevine

Finally:

sudo pipelight-plugin --enable silverlight

Then update Pipelight to recognize these plugins.

sudo pipelight-plugin --update

Finally, you must add the plugins to Firefox.

sudo pipelight-plugin --create-mozilla-plugins

Testing it out!

If done correctly, Pipelight should have installed an update version of Flash, Silverlight, and Widevine, which it runs through Wine, as can be seen in the Plugins section of the Add-ons Manager.

Finally, open up Firefox and test 'er out.

Pipelight solution does not work at the moment, but Firefox with Flash on PlayOnLinux does.

1. Install and run PlayOnLinux

sudo apt install playonlinux

playonlinux

2. Click Install and search for Firefox

3. Select Flash when prompted
4. Run Firefox

5. Go to HBO website and if the videos still do not work, install the Flash they link to.
