Here is another way to grant camera and microphone permission to a site. While you are on the relevant page, you can call up the Page Info dialog using either: * Ctrl+i (for Mac, Command+i) * right-click a blank area of the page > View Page Info * (menu bar) Tools > Page Info When the dialog comes up, click the Permission icon at the top to show that panel. Scroll down to "Use the camera" and uncheck the "Use default" box, and then select "Always ask" or "Allow" depending on your trust for the site. Repeat with "Use the microphone." That is saved immediately, so you can just close the dialog at that point. When you reload the page (Ctrl+R or use the original launch link again), Firefox should now apply the new permission. Does that work?
