Update (today's date is 1-21-2020): Shortly after I left this review, I switched to Waterfox (which since became Waterfox Classic). Back then, the sounds were working beautifully with Firefox Quantum. I switched back to Firefox just over a week ago (on January 12th) and unfortunately, Mozilla changed something and now Extra Sounds gives me FAR too many Navigation Start clicks, and sometimes they can be too loud. I don't know what Firefox is doing that's so different from a year ago, but good lord. They made Extra Sounds become annoying!!! It breaks my heart. Those bastards. lol Oh well.

Fortunately, I'm actually finding that I'm happier without the sound. Go figure. I guess I've changed! :) Thanks again for your hard work, Jawhien. It's been a damn good run!

Original review below:

This is awesome. I might actually switch to Firefox Qauntum thanks to this (from Firefox 52.3.0 ESR).

I've been using Firefox Quantum as my Amazon Prime Video player ever since Amazon raised their minimum browser requirements (it made me quite angry because I hate Firefox Quantum). My primary browser is Firefox 52.3.0 ESR. One of the many reasons I refuse to switch to Firefox Qauntum has been that I couldn't find a Navigational Sounds equivalent. I've had that feedback sound for as long as I can remember (since Windows 95, I guess, I'm not really sure). So, I kinda depend on it.

Well Jawhien, thanks you to, a major roadblock between me and Firefox Quantum has been removed. There are still a few remaining (I'm finally working on removing them one by one), but this one was probably just about the most difficult one for me to deal with since Quantum's release, and now I no longer have to! I'm very happy. Thank you!

Consider this a very big and warm bro-hug from me to you, man. It's just that big of a deal for me.

Thank you so much !! Basically the same as the old navigational sounds in old firefox.
