hello, I wrote to you telling you that when i facetime on facebook i cannot see or hear anyone and you answered me to try this or that. you said to go into permissions and make sure that my camera and microphone had facebook to have permission and when i facetime to go into permissions there and click off the use default button and click allow or always ask. i have already done this and still have the problem. well I know what is happening and it is your fault firefox. when my sister, who is sitting next to me rings me on facetime (and was helping try to fix this problem) and it still didn't work, while she just kept the facetime open, she watched me go into the permission box again on the padlock page, the settings i put ALLOW were gone and the use default box was ticked again. so this time i put always ask. and came back out of the permissions page and then went straight back in, and guess what.....every time i leave the permissions page, it goes back to use default. MY SETTINGS ARE NOT BEING SAVED. THERE IS NO SAVE BUTTON BECAUSE YOU REMOVED IT. I MAKE A SETTING, COME OUT OF THE PAGE AND IT IMMEDIATELY REMOVES MY SETTINGS. YOU NEED TO FIX THIS BECAUSE NOTHING IS WORKING BECAUSE IT CONTINOUSLY GOES BACK TO DEFAULT. IF YOU DO NOT FIX THIS ASAP I AM SHUTTING YOU DOWN AND GOING TO BING AS MY BROWSER
Here's the thing Mic/Camera is controlled by the O/S first and that must give those apps permission so you need to double check the O/S permission settings to insure that is allowed otherwise no matter what you do in other app if the O/S denies it those apps won't be able to use it.
