Attached image Gif showing the issue
Affected builds:
- Firefox 43.0.3 RC build 1
- latest Nightly 46.0a1
- Firefox 34.0 RC

Affected OS's:
- Windows XP

STR:
1. Start Firefox
2. Visit https://twitter.com/
3. Login to account
4. Scroll down the timeline to a GIF.
5. Click the GIF
6. Repeat step 5.

Expected results: The gif is played and stopped if clicked and comments are shown.

Actual results: The gif disappears and if clicked a few times, the comments will stretch to the next tweet from below.

Notes:
1. This is not a recent regression, reproduces with Firefox 34.0 RC as well. Will try and find a regression though ASAP.
2. Attaching the gif, showing the issue.
3. Based on bug 1234513 comment 3 it seems that this gifs are actually short videos so that's why I'm logging this bug in this component.
Here is a regression range, the good build is a build where clicking the gif, images and other buttons will do nothing. On older builds I can't login, because the password field does not work at all.

Will add regression keyword despite the old and unreliable regression range.
Keywords: regression
Component: Audio/Video → Graphics
Hrm, I'm not entirely certain this is graphics. Might very well be related to FrameLayerBuilder. What do you think Matt?

It does sound like a layout issue, nothing really stands out in the regression range though.

Is it possible to get a narrower regression range? Will probably need someone to do local builds.

Yes, Twitter "gif"s are actually H.264 videos. Firefox have never supported H.264 on Windows XP.
Twitter should fallback to Flash if the browser does not support H.264. Do you install Flash?

I can try and set up my XP for building Firefox locally but I think it will be quite painfull to do that.

Yes, I have latest flash version installed on XP.
Can we tighten up the regression range per comment #3?

This does not apply anymore since twitter made some UI changed on their side. I checked on Windows XP 32-bit using latest Nightly and gifs are played just nice.
