Rated 5 out of 5 stars
Sound events can be very useful to persons with various visual impairments. Up until now, the only option that I'm aware of is Popup Sounds which is a good extension but it only allows for 3 specific sound events.
Soundsnap.com has thousands of free sound samples that you could use and offer in Noise or at least direct Noise users to it.
This is a great add-on and I appreciate the time and work that you put into it.
Thank you for your interest in this extension.
Normally it's not necessary to restart Firefox to apply settings. so I'm afraid that is a bug (but I can't reproduce it)
And about a supporting forum, currently I choose google groups to help it. And manage FAQ or HOW TO on a homepageURL by myself. Not sure this is a good way. If everyone has any ideas, please feel free mail me or something, thanks!
