find a way to disable animated personas


(Firefox :: Theme, defect)

Not set





(Reporter: Gavin, Unassigned)


Bug 650968 kind of did this half-way: once we apply the cropping, we lose the animation (since we just crop the first frame). But there are still cases where we show the animation (e.g. during preview, before a restart), and so that leads to inconsistent behavior (bug 819190).

I'm not sure what the best way to do this is - perhaps a CSS style that prevents an animated image from being animated?
How about cropping the image right after installing?
That doesn't help with preview though - we can't do cropping on the fly like that. I spoke to #gfx about this and Seth suggested that it may be relatively easy using the temporal media fragment he has been working on. I think he was going to file a bug about that and land it relatively soon.
If we could add a CSS property to disable animations, that would probably be incredibly useful to certain extensions.
I've opened a bug for supporting temporal media fragments for animated images at bug 821571.

We stopped calling the theme based "Personas" that name several years back, when they were also integrated into normal themes in Firefox.

Therefore bulk-closing Persona related bugs as they are no longer valid. If you are still having a potentially related issue in the latest version of Firefox, please take a look on our support site ( or file a new issue.
