Youtube app is not installed. Flash is not installed. The default Android browser (“Browser”) can simply play the videos inside the webpage, but Firefox simply shows a black screen with no in-page or any other playback. This is similar to user “yumiko”’s problem that has not been solved. Why does Firefox lack in-page playback of YouTube videos?

I would guess that you don't have the YouTube app installed. We kick out to the YouTube app on m.youtube.com. The workaround is to use a desktop user agent. Which can be done by installing https://addons.mozilla.org/en-US/android/addon/phony/

Thanks for your reply, kbrosnan. It isn’t very helpful, though.

I said so in my original post right at the outset.

Why? The Android “Browser” doesn’t do this, and can play videos in-page just fine. Can’t FF hae at least a configurable setting to enable/disable the default use of the YT app? This counts as a bug, IMHO.

Switching to a desktop UA doesn’t help, as it loads the (heavy) desktop version of the site, with high-bitrate videos, rather than the mobile-optimised narrow-format site with low-bitrate videos.

As for your issue, FxAndroid doesn't lack this ability. m.youtube.com loads fine for me in-page. Did you recently install any new addons? You can see them at about:support and click Copy raw data to clipboard then paste it in a new comment.

Thanks for your reply, Moses B.

Congratulations if FF plays videos in-page just fine for you. It doesn’t for me.

I’ve no addons installed at all.

I think I’ve found a bug report dealing with this issue here: https://bugzilla.mozilla.org/show_bug.cgi?id=906869

I asked about the work around suggested in the bug that you found, however my question is is Phoney supported for your device? https://addons.mozilla.org/en-US/mobi.../phony/

guigs2,

> is Phoney supported for your device?

No idea. I decided against installing that addon after reading this problem with it: https://addons.mozilla.org/en-US/mobile/addon/phony/reviews/521029/ (Breaks addons.mozilla.org). Theoretically, there’s no reason it shouldn’t work.

However, the report on using that “workaround” (post #13 on the bugzilla page) is not so good. FF does not emulate all rendering quirks of “Browser,” so doing its own thing is a Good Thing. That, unfortunately, requires the YT App, which is patently ridiculous.

Update: This bug is still present on Firefox for Android 30.0 (from F-droid). Fortunately, it is being tracked at https://bugzilla.mozilla.org/show_bug.cgi?id=936851

Let’s hope it is quickly and satisfactorily resolved!
