Firefox won't open

I'm on a iMac desktop. Today I downloaded & installed Catalina OS 10.15.2. And Firefox has not opened since. It goes through the opening process with the icon going up and down. Then it stops, indicating it's still not open. When I right-click the icon it says it's not responding and I have to "Force Quit" to get it to close. I'm mystified. I can't find anyone else having the same problem.

To both of you, thanks for your input. The problem seems to have solved itself. It just started working normally. Not sure what was holding it up. But there was definitely a problem that I had not seen before. Thank you for chiming in.

Is Catalina running otherwise fine on your iMac? Seems so strange for it to single out Firefox. I have an idea to see if it can run a Nightly or Beta version of Firefox just to see if that will work.

Also apologies for not giving you a response sooner! It's the holidays & we've been trying to balance taking time off & helping you in our free time :)
