I've loaded Firefox and when I double click on the icon nothing happens.

I've removed the Firefox program and re-loaded it 3 times. When I double click on the icon, Firefox will not open at all.

This happened

Every time Firefox opened

Soon as I loaded the Firefox software

Hello Diana.

Unfortunately, this kind of problems are the hardest to fix because they're the hardest to diagnose. For now, try reading this support article:

I hope it helps.
