Are you talking about the viewing a YouTube video in the Gaia video app?

Can include a screenshot? That will tell me immediately how you are viewing the video.

The view was launched when i selected a video from my home page. Now the problem how to navigate back to the previous page.

I'm going to guess this is in reference to the current Gaia Video implementation with YouTube videos, unless you are using a custom HTML 5 URL for YouTube videos. The current Gaia video implementation should have a back button. You should see it if you click the video while viewing it in the upper left hand corner. If it's not there, then this is a regression.

Oh wait, disregard my comment 4. This is regards to going to the detailed video page and trying to navigate back. That's a TE issue, although that's an issue on all browsers, not just FF OS.

However, I'm going to WONTFIX this because this applies to all platforms and a not a new TE issue specific to Firefox OS. The expectation in the YouTube app is to do navigation through the menu and searching that is already present in the UI.

I agree with your comments, but in case of browser we have the back button present which enables to navigate back from any pages. This will work even for B2G browser. In case of this application aren't we missing that.

What do you think?

That's a fair statement. I just wonder if this is going to be a tough sell to YouTube to change something that isn't a gecko-specific issue - it's a feature request on their mobile site. I can reopen to track under the TE bug, but I'll have to see if YouTube willing to fix this.

Donovan is driving the communication on this, so I'm redirecting the needinfo request to him.

YT is unwilling to add the back button to their app. Is there any way we can get the platform to provide the back button, like everything.me provides to apps, perhaps if some special flag is present in the manifest file?

It's a one line patch to add a manifest attribute which enables the navigation ui. The name of the attribute is up for discussion. The patch is so simple I'll just paste it here:

--- a/apps/system/js/window_manager.js
+++ b/apps/system/js/window_manager.js

895826 is fixed, YouTube has the correct key in their manifest file, and I verified that the navigation bar shows up and is available on the phone. Fixed.
