Download Adobe Flash Player Update 11.8
Even though I have the latest Adobe Flash player 11.2 for Linux in Firefox - ref: Flash player security doubts - a particular online flash game still requests that I update to the latest flash player.
To install the latest version of flash player search the Dash (in Ubuntu releases before 17.10) or the Show Applications dashboard (in Ubuntu 17.10 or later) for Software & Updates and open the Software & Updates window. Click the Other Software tab in the Software & Updates window, and put a check mark in the checkbox to the left of where it says: Canonical Partners.
Flash plugin for Linux provided by Adobe stopped at version 11.2. For Chrome/Chromium users there is Pepper Flash plugin, but it's not supported by Firefox/Iceweasel/other browsers. In Ubuntu 16.04 and later browser-plugin-freshplayer-pepperflash from the default Ubuntu repositories allows one to use the Pepper Flash plugin from Chrome in Firefox and any other web browser supporting NPAPI plugins. It works better than adobe-flashplugin in Firefox.
Also, you might want to run sudo pipelight-plugin --update from time to time, so that Pipelight will know to install an updated version of flash player. This both prevents Pipelight from trying to download plugins from dead links, and ensures said plugins stay up-to-date. Or, you can create a cron file to run the command automatically. To do this, run sudo bash -c 'echo -e \#\!"/bin/bash\n\npipelight-plugin --update" > /etc/cron.weekly/pipelight-update; chmod a+x /etc/cron.weekly/pipelight-update' This will allow your Pipelight's list of plugins to be updated weekly, although the actuall plugins won't be updated untill you start your NPAPI-based browser.
The above link will tell you how install FreshPlayerPlugin by cloning a git repository and compiling the code yourself. Or, you can install the pepflashplugin-installer package from the skunk/pepper-flash ppa: sudo add-apt-repository ppa:skunk/pepper-flash && sudo apt-get update && sudo apt-get install pepflashplugin-installer. See the bottom of THIS page for instructions on how to enable Chromium to use pepperflash. Warning: this depends on Google Chrome support. Please see update #3.
Save the tarball into the /tmp folder with the name flash.tar.gz. If your browser automatically downloads the tarball, thus making it impossible for you to rename the tarball before the download starts, wait for the download to end, then go to the folder where the tarball's been put, rename the tarball to flash.tar.gz and then move it to /tmp.
You can now run your Mozilla/Gecko browser (Firefox, Iceweasel or SeaMonkey) and then access the URL about:plugins in order to check if your browser has detected the flash plugin located at /usr/lib/adobe-flashplugin/libflashplayer.so (it should be also visible by accessing about:addons and then the Plugins section). If you see something like Shockwave Flash 24.0 r0, then go to in order to check if the flash applet detects your NPAPI flash install and tells you which version you're currently using.
Save the tarball into the /tmp folder with the name pepflash.tar.gz. If your browser automatically downloads the tarball, thus making it impossible for you to rename the tarball before the download starts, wait for the download to end, then go to the folder where the tarball's been put, rename the tarball to pepflash.tar.gz and then move it to /tmp.
You can now run your WebKit / Opera browser (only Opera versions prior to version 45), then access the URL about:plugins in order to check if your browser has detected the flash plugin located at /usr/lib/adobe-flashplugin/libpepflashplayer.so.

If you're using Google Chrome/Chromium, it already comes with its own bundled PPAPI Flash plugin located at /.config/google-chrome/PepperFlash/some_version_number/libpepflashplayer.so. However, if videos aren't working with Google Chrome/Chromium when you're on Facebook, YouTube et cetera (you hear the audio, but doesn't see any video), then you're probably trying to watch HTML5 videos but your GPU (Graphics Processing Unit) has a built-in rendering blacklist that's avoiding video acceleration required by HTML5.
If e.g. your Chrome/Chromium browser is using PepperFlash plugin version 18.104.22.168 and you downloaded Adobe's flash PPAPI plugin version 22.214.171.124 (same version of Google's PepperFlash), then this is the shell command you'll have to issue after you install Adobe's Flash PPAPI plugin:
