• Superuser.com - How to circumvent to disablement of flash plugin

1. Download and install an older version of Firefox, e.g. version 51
2. Install flash plugin
3. Create a separate user profile for this installation
4. Symlink libflashplugin.so to <user-profile-dir>/plugins/
5. Edit /etc/adobe/mms.cfg and add the following lines:

   AllowListUrlPattern=https://example.url
   EOLUninstallDisable=1
   

   You may specify AllowListUrlPattern multiple times for multiple urls. AllowListUrlPattern=* or AllowListUrlPattern=https://* won't work
6. Start Firefox with new profile like this: </firefox-path>/firefox --profile <profile-path> --no-remote
   • Use --no-remote to create a new window in a new session
   • Otherwise an already open Firefox would spawn a new window
