When typing a word it makes a noise and completes the word
When I typed altalthough, it completed the word while I was typing. You can see what happened to the word. It makes a noise when it does it, also. I've got the latest version of FF for Win 10.

It sounds like a problem with a spell checker or auto compleate. Note: Firefox does not use sounds, but add-ons and other programs do.
