loss of sound in add on extension check4change

Steve Siegler

How do I get sound back on the add on extension "Check4change" ? it has always worked and then stopped one day. I have tried all the suggestions of reloading the extension and even removed and reinstalled Firefox, it was no help. I have sound in Firefox, just not while using the check4change add on extension.

How do I recover sound while using the extension?

Hello Steve.

Please provide that feedback to the developer of the extension. You can do so using their Support Site or Support Email on their listing page; https://addons.mozilla.org/en-US/firefox/addon/check4change/.

Hope that helps -- Ed
