@2433bcdf Thank you. I also noticed that about:pforiles does not work.
@a74d0fe0 Typos. The bane of our existence. 😂
@2433bcdf @a74d0fe0 You can also start Firefox with a specific Profile. Firefox.exe -P "Profilename" or Firefox.exe -new-instance -P "Profilename" to get a new instance. Create a shortcut on your Desktop and you are good to go. You could also hack the registry and extend the std apps with the command line options. HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.html
