[Note] Run Flash in year 2021

All latest browsers and Flash player itself stopped supporting Flash sites by end of 2020.

This note is to enable Flash (at your own risk) for special circumstances.  For my case, it's to run Oracle 18XE EM.



Run Flash site in year 2021.


Ubuntu 20.04, 64 bit


Oracle 18XE EM still uses Flash.  I prefer GUI over console to do occasional Oracle DB admin tasks.



  1. Get an older version of Chrome and install
  2. Get Flash Player and install
  3. Install some Ubuntu packages
  4. Configure flash/chrome/Ubuntu
  5. Run chrome and set up for Flash site within the browser

Chrome - download and install

  1. Go to
  2. I downloaded 79.0.3945.88 version:
  3. It will save as google-chrome-stable_current_amd64.deb
  4. Install:
    $ sudo apt install ./google-chrome-stable_current_amd64.deb
    This will install the program in /opt/google/chrome/

Older Chromium may work, but I didn't try.  You can get it from here:

Flash - download and install

  1. Go to
  2. Download GZIP ->  flash_player_ppapi_linux.x86_64.tar.gz (9.3M) 
  3. Uncompress it and put the files to a folder in /usr/lib/adobe-flashplugin/

(2016) $ ll

Configure Chrome

This is to use the flash player.

  1. $ vi /usr/share/applications/google-chrome.desktop
  2. Change Exec= entry like this:
    Exec=/usr/bin/google-chrome-stable -ppapi-flash-path="/usr/lib/adobe-flashplugin/" --ppapi-flash-version= %U


Install Ubuntu Package

We need supporting packages.

$ apt install adobe-flashplugin browser-plugin-freshplayer-pepperflash


Configure Chrome+Flash to run Flash site

Create two mms.cfg files in two different locations:

$ vi /etc/adobe/mms.cfg
$ vi ~/.config/google-chrome/Default/Pepper Data/Shockwave Flash/System/mms.cfg

Add content like this:

$ more /etc/adobe/mms.cfg
# Disable Automatic Updates
# Disable prompts to uninstall Flash Player
EOLUninstallDisable = 1
# duplicate actionscript console output
# in browser's console for javascript
# Enable the AllowList feature
# Normally, the allow list blocks URL requests
# unless the url matches a pattern in the list.
# In preview mode, all requests go unblocked,
# but console output is written for each request
# indicating which pattern it matched or that
# no match was found.
# Pattern to enable Your OEM:


Allow Flash for a site in browser

  1. Run Chrome
  2. Open these two sites as configured in mms.cfg
  3. Pass security warning and proceed to the page (if EM page)
  4. Click on padlock icon and change Flash to Allow.

Do not update Flash or Chrome browser.



  • Was it worth it?  It was fun to find a solution, and now I can use Oracle EM.
  • Better way?  Upgrade Oracle to a higher version that EM doesn't use Flash.  Or, use command line instead.
