Status: RESOLVED DUPLICATE of bug 129986

(Core :: Graphics: ImageLib, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.2) Gecko/20100115 Firefox/3.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.2) Gecko/20100115 Firefox/3.6

Firefox doesn't rewind a loopless animated GIF when a page containing the GIF is revisited. It even doesn't rewind the GIF animation when page content is refreshed (standard [F5], not full refresh [CTRL+F5]).

Reproducible: Always

Steps to Reproduce:

Load the GIF addressed in above URL. It contains 5 frames which are only played once.

Actual Results:  

The animation is only played once. Re-entering above URL or hitting refresh doesn't rewind animation playback.


Expected Results:  

The animation should rewind when a resource is revisited/refreshed.

Well, ctrl+f5 works fine for me. It doesn't replay with just a refresh though.

Right, I haven't been clear on this distinction in my statement.

But no-one should feel impelled to hit <CTRL>+<F5> everytime he/she visits the page.

I'm almost certain that this is a dupe, but I can't find it right now.
