I have used Firefox for the past two years. Over the last two months, I have to delete and reinstall the app on my MacBook Pro because the app will not launch. Now, after reinstalling the app, it won't launch at all. If I click the app on Launchpad, the app will pop up on my app bar, it will bounce a few times and then disappear. I'm very frustrated because I use Mozilla to launch timekeeping and payroll. Any help and guidance that you can provide would be helpful. Thanks in advance!

Warm regards, Ana
