I'm using macos 12.5 Firefox will not open any windows. When I try to open Firefox by clicking on the dock icon, nothing happens. If I right-click the dock icon and select 'Show All Windows", a message takes over my screen. The message says "No Available Windows". I manually deleted the caching directory in my homedir. I then deleted Firefox, downloaded the latest version and installed it. Attempting to open it fails again. The same symptom recurs. I'm running the latest version - I downloaded it about 20 minutes ago. But I can't find the version number because the application won't actually open.
