If I open Firefox or Thunderbird or any other application twice, they stack on top of each other in the dock. I run GNOME 3.36
on Ubuntu 20.04.1 LTS
.
How can I duplicate the icons of the applications that I open, on the dock?
This is especially useful when using multiple screens, so that I can easily switch between opened apps without having to select which Firefox instance I want to show on the main screen, since the second one always runs on the second screen.
The dconf-editor
did not seem to have any option that allows me to run multiple icons instead of stacking the icons.
