These days browsing through some sites firefox asked me to access to my mic and camera... According to you, why?

I think (and I hope) that was because of some specific sites...

Either way the website asked for it or some plugin I think. I would never allow it tbh if I were you

@8BitOverdose in fact I didn't. But it scaried me though

I'm just ondering why on Earth should a plugin or the website get access to that...

Camera? I have no clue.

Mic? Maybe there's some accessibility based feature for voice search. Doubt it, but that's my most logical guess.

@dmonkey One example I can think of is when you want to face voice chat on Discord in browser.
But I'm sure it's nothing.

If I'm not mistaking it could also be asked by Firefox itself after an update. So I'm sure it's nothing and you shouldn't worry as long as you don't have shady plugins installed

Same reason as why some sites ask for your location.

@2lazy2debug I think so. Trying this on a browser console does popup the website's name.

navigator.mediaDevices.getUserMedia({video: true});

@2lazy2debug The case in mobile apps is the page will not be able to directly access those features, only the app is allowed by the system, then the app hands over those things to the web page, it can listen to the JS interface and hands over voice recorded and frames captured by camera back to web page.

But FireFox should at least say the web page wants them, cuz that dialog in the image is the default system dialog when any app asks to use features that require permission from the user, it was not programmed by FF devs

@2lazy2debug oh sorry I thought you were asking why, my bad bro :D
