I have both speakers and a headset on my desktop. The system has worked fine for the past 1.5 years. Suddenly today, when I unplug by headset and select speakers for audio, it works for other apps, but not on Firefox browser. Can someone offer some possible reasons for that and, even better, as solution?

Hello; I installed a new web page. While the page opens properly in browsers such as Safari and Chrome, in Firefox it constantly displays 403 forbidden Access to this resource on the server is denied! gives an error. I deleted the caches. I did flush DNS. I even reset firefox. I tried everything but the page still gives an error. There is only a dry WordPress content. How can I get rid of this error? Thanks.
