Is there any Adobe Flash Alternative which runs Actionscript 3 on Browser?

I am an Engineering student and due to this pandemic, I was asked to do a virtual simulation of a lab.

.

I am using a ubuntu 20.4 machine and I use both Chrome and firefox. Theabovelinkis the simulation and It runs by adobe flash and hence unable to access it. I have used ruffle but ruffle doesn't support action scripts 3 which is why I am unable to click buttons and all on the ruffle emulated page.

Please help me with a way to get this work on my browser. Thanks in advance

You can still install Adobe Flash Player (warning - it is EOL and insecure) using some archive links and hacks:

cd ~/Downloads
wget -c
sudo apt-get install ./flashplugin-installer_32.0.0.465ubuntu0.20.04.1_amd64.deb
sudo wget -c -O /var/cache/flashplugin-installer/adobe-flashplugin.tar.gz
sudo /usr/lib/flashplugin-installer/install_plugin adobe-flashplugin.tar.gz

then pin its version to prevent upgrades by using single long command:

cat <<EOF | sudo tee /etc/apt/preferences.d/pin-flash
Package: flashplugin-installer
Pin: version 32.0.0.465ubuntu0.20.04.1
Pin-Priority: 1337
EOF

Then install

• local old insecure version of Waterfox (Firefox fork) browser:

  cd ~/Downloads
  wget -c
  tar -xf waterfox-G3.2.3.en-US.linux-x86_64.tar.bz2
  sudo chown -R root:root waterfox/ # prevent auto-update (optionally)
  cd waterfox/
  ./waterfox 

• local old insecure version of Firefox ESR 52.9.0 from FTP:

  cd ~/Downloads
  wget -c
  tar -xf firefox-52.9.0esr.tar.bz2
  sudo chown -R root:root firefox/ # prevent auto-update (optionally)
  cd firefox/
  ./firefox 

and enjoy.
