I tried this video on my Nexus 4 (Android 4.4.2) and the video plays fine with Fennec Nightly 35, Fennec Beta 33, and Fennec 31. This will probably need testing on an LG G2 device to confirm.

Kevin, do you have access to an LG G2?

Aaron, do you have an LG G2?

No.

This should be resolved by bug 1014614.

I just got my LG G2 and am able to reproduce this. I'm assigning myself as QA contact to test this again once bug 1014614 is resolved.

Bug 1014614 just got checked in to mozilla-central. Flagging myself to test this with tomorrow's Nightly build.

Testing is blocked by bug 1085405.

Nevermind, I was able to work around bug 1085405 and the video now plays fine. Marking this fixed.

Verified fixed by bug 1014614.

[Tracking Requested - why for this release]: Nominating this to track and marking this as affecting all current branches. However, I think the fix here might be too risk to uplift. We should probably just let it ride unless there's a high volume of complaints around this issue.

Given that the fix was delivered in bug 1014614, I don't see much point in tracking this bug. Given that we're still early in Aurora, it may be worth uplifting to 35.

I updated to FireFox 34 and still seem to be having the issue with my LG G2 device. Should I update the branch of the version of the ticket to 34?

No that's fine. We pushed a fix targeting Firefox 36 which is currently Nightly (http://nightly.mozilla.org) over in bug 1014614. You can try that out on your device by installing Nightly for Android (it uses it's own profile).

In addition to what Aaron said, we did not address this bug directly. The patch which solved bug 1014614 had a mitigating factor which means this bug no longer reproduces. I suspect bug 1014614 to not be fixed in Release until Firefox 36 as it's a pretty extensive change and needs proper testing. 

Unfortunately that means this bug will go unfixed until then as well and there's nothing we can really do about that. If you cannot wait, you're free to try Nightly as Aaron suggests but know that it's potentially more prone to bugs as there are changes landing every day.
