mail sound in linux mozilla
I was getting irrationally annoyed that Linux Mozilla didn't have a properly implemented mail sound, so that I was just getting a PC speaker beep when I got new mail. It may be petty, but it was very much getting on my wick, particularly as the bug has been noted for ages.
Anyway, if you're in a similar situation, I just thought I'd say that I found a program called softbeep
that traps and redirects beeps, so you can play a custom sound. As far as I can see, it works well.
