The installation on my win 11 laptop is doing some odd things (1 - recently lost all extra (unselected) windows on restart, even though set to restore all windows and tabs and 2- opening a new window creates an outdated duplicate of the window I already have open instead of just creating a new window with an empty tab??). So I thought I'd try refreshing it. Well, my "More troubleshooting" page does not have the "Refresh Firefox" button, only the "clear startup cache" appears along with option to run in troubleshooting mode. No Refresh option in teh same page in troubleshooting mode either. I am using the Microsoft Store MSIX installation. I am thinking about uninstalling that one and installing from a Mozilla download instead??

What would be the best way to clean up my installation state since the refresh is not available?
