Why is my camera not working, even when it's enabled through Firefox?

Hi, today I was supposed to take an online midterm using ProctorU. Unfortunately, I had to switch to Edge (gross!) because despite Firefox having complete access to my camera always, it won't show it. I've used multiple webcam test sites and noe seem to work. The light on my camera turns on, but I just get a flashing red camera icon in the nav bar. My camera works with the native app, it's allowed through the firewall, AdBlock is off for these sites, and in about:config, media*enable search is all set to default.

Flashing red it should be a blue light if it is working correctly. That's what my webcam does.

Lol, yeah I'm aware. It IS functioning in Edge, but no picture shows up in Firefox (or Chrome for that matter).

That would indicate hardware communication problem.

So it would indicate, but again, the camera functions perfectly in the native app and in Edge. When Flash asks for permission and I give it, nothing shows up, which indicates a *software* problem, either within Flash or within Firefox itself.

Hi, please check here : Copy/Paste about:preferences#privacy to the Address Bar then Enter. Go down to Permissions --> Camera and Click Settings and see if that web site is in there and if Blocked, also look at bottom of that for Check Mark in Block new Requests ..... and if there is please remove it.

Please also try in : SAFE MODE as Adblock may cause the issue or the 2 Flash you are running.

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Advanced > General)
  • plugins are not affected
  • preferences are not affected

Hi, I tried everything above, but I still have the red camera icon. I think it's worth noting that one of the sites I'm testing with also tests my mic. It can detect the mic levels but it also flashes with a red mic icon.

Anything else I can try?
