I am running Firefox on Kubuntu, which means it comes pre-installed as a Flatpak. I was having problems with various web sites so I decided to try using the version of Firefox installed with the file found here - https://www.firefox.com/en-US/thanks/ There were no problems with the install. This version of Firefox showed the same issues as the Flatpak version, so I blame the web sites. Now I have two versions of Firefox. I would like to remove this second version but all the methods I've found do not remove it. I can certainly disable it by renaming the directory created in my user directory /Firefox. Trouble is, shortcuts I created to web sites always launch this version rather than the Flatpak version and I can't find a way to get the shortcuts to use the Flatpak version.
