My OS is Catalina 10.15.4. Firefox worked fine until today. I have removed and reinstalled Firefox. I have setup a new profile. Firefox will not open in safe mode.

What else should I do?

I tried that but it didn't help. The video refers to an executable that has somehow corrupted to a txt file. I ran the terminal routine but it didn't help because I think the firefox file isn't corrupt. The firefox executable in my package contents is a Unix executable.

Hi, hold down Shift (Option key on Mac) when you start Firefox to start in Safe Mode. ... You may need to restart Firefox after enabling some add-ons. Try starting from the Start Menu > Mozilla Firefox. If it works; in Win10 you can drag from the Start Menu to your Desktop or right click and pin the icon in the Task Bar.

Thank you.
