I have just started a new job and installed the Firefox browser on my PC (W11) as part of setting up my new workstation. The application works fine until I get a message that Firefox needs to install an update, 'please close it or it will close automatically in one hour'. After the update I get a message that the update is complete and you can restart the application, but the application no longer works; the icon on the application list no longer works 'The item firefox.exe that this shortcut refers to has been changed or moved'. After re-installing Firefox it works OK again, but the process repeats. Although I have managed to succesfully update a new installation on two occasions, after a few days the process repeats and I need to re-install again.
