Steps to reproduce:

When I go to Menu->Tools there is no tab mirroring option. I tried mirroring a video but there's no chromecast icon. I am using Firefox Beta version 35 for Android and also tried Firefox 34 (non beta). I am on a phone with Lollipop. 

I tried Firefox on a tablet with kitkat and have the same issue. In Firefox 35, if I go to about :devices I see my chromecast along with its ip address. In the Android chromecast app I see my chromecast device and can chromecast from other compatible chromecast apps

Actual results:


Expected results:

My tab should have been mirrored to my chromecast
Can you provide the video that you tried to mirror? Do you see the option on other websites?

This is the site I used to test mirroring: I also tried YouTube in desktop mode. The video played just fine in Firefox but there wasn't a chromecast icon

What about other sites with just text for example?

Same thing the mirroring option isn't there
Can confirm it with 35beta. 34 stable on the other hand has the mirror option available
Can confirm. I am using my Chromecast today and there is no availability in media nor in the ability to mirror a tab in product.

Looks like trunk Nightly is fine, Aurora (36)/Beta seem to be affected. Only on trunk do I see mirror tab and have the ability to cast a media (e.g, MP4). On Aurora/Beta, all those options are missing.
Actually hold that. All of a sudden now I am seeing the ability to cast (35) and mirror (36) now in the Beta/Aurora. I'm not sure what I did, but I assume initially it did not find the device on my network.
This works for me. I rebooted my Chromecast, I ensured the browser sees my devices (about:devices), I connected Chromecast in the Chromecast application and I can't reproduce. I did initially see the inability to cast but I can only guess that the browser didn't see the device. WFM/

I had the same problem with Mirror Tab not being visible in Firefox 35.  Based on the previous comment I tried about:devices and surprisingly found my Chromecast listed.  I tried looking in about:config and found browsing.mirror.enabled was set to false.  I set that to true, did a Force Stop, and mirabile dictu Mirror Tab appeared.  Seems to be working reasonably well for me on a 2013 Moto X.  It appears to respect portrait and landscape but only when set prior to mirroring.
Even though I can Chromecast, I think Mirror Tab/Stop Mirroring should be shown in menu, I don't see it at all in Firefox 35.

Are we supposed to be showing 'Mirror Tab' in the menu on 35?

We have two preferences for controlling mirroring on Android:


The first should control all aspects of mirroring. The second should control whether the Roku supports mirroring. Both are | false | on Release builds.

Since Chromecast support mirroring, I assume we should make "browser.mirroring.enabled" = true everywhere.

What do you think Brad? Also, should Desktop use similar preferences?

Yea, it probably should

Let's enable mirroring in all channels
