A 3 tone sound played, what is it?

Today I had only Firefox open on my Mac and a sound played that I can't find the source of. It was 3 notes, with the last note being the highest pitch. It worries me that something happened and I can't find out what.

When this happened I quickly rebooted my Mac and then updated Firefox to the latest version (I had the version before the latest, I believe.) But I still would like to know what the sound means.
