"No available windows"
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.
