Why there is no "always allow" option in Firefox when using `getUserMedia`?

Question

I'm using getUseMedia function in my app. Every time I open Firefox permission popup appears. There is no always allow option.

According to the Bugzilla the feature is already implemented at Firefox 30 - current version is 43.

I'm using getUserMedia like this:

    navigator.getUserMedia = (navigator.getUserMedia ||
    navigator.webkitGetUserMedia ||
    navigator.mozGetUserMedia ||
    navigator.msGetUserMedia);

Is it right? Why I can't select allow always option?

Answer 1

As you seem to have discovered, Firefox, like Chrome purposefully disallows this functionality without HTTPS.

Mozilla's tests are a great source for answers around desired behavior, in this case: "'Always Allow' ignored and not shown on http pages"
