They work fine for me, in both Firefox 3.6 and on trunk.

Just to check, are your image animation preferences set to not animate or animate once or something?

I can reproduce this under the following conditions:

1) Firefox 4 beta Mozilla/5.0 (X11; Linux x86_64; rv:2.0b7pre) Gecko/20100930 Firefox-4.0/4.0b7pre

2) The animated gif is in a web page. 

3) The HTML web page is reloaded using F5 (or clicking on the reload button).

If I drag the page onto the browser, the animation will run. If the page is reloaded, the animation will stop. The animation will not restart unless I drag the web page onto the browser again. I don't have any problems with Firefox 3.6, so this seems to be new to Firefox 4.

If I simply load the animated GIF in the web page directly (i.e. not part of a web page) the problem does not occur even if the GIF is reloaded. It must be part of the web page for this problem to occur. 

I discovered this problem when testing a web application I am working on. I'm using an animated GIF as a "spinner" while the page is waiting for a server response. In that case, when the animation is stopped I have to close the browser completely and re-open it. If I navigate away from the page and return to it, the animation is stopped and won't restart unless the browser is closed and re-opened. 

I am posting this here because I *think* the problem I am seeing is the same as originally reported here, but the original description left out the fact that you need to be using the GIF in a web page. I used the animal0028.gif file in this test, but I discovered the problem when using my own GIF file. 

I can supply a test web page if required, but the above mentioned GIF and a very simple HTML 4 or HTML 5 web page illustrate the problem quite easily.

As a correction to my previous post, where I said:
"If I simply load the animated GIF in the web page directly (i.e. not part of a web page)" 

I actually meant to say:
"If I simply load the animated GIF in the web *browser* directly (i.e. not part of a web page)".

That is, I don't see the problem if I load the GIF file directly in the browser. I do see the problem if the GIF is loaded as part of the web page.
> I don't have any problems with Firefox 3.6

Then you're not really seeing this bug, which was filed against 3.6.  Would you mind filing a separate bug on your issue (and ccing me)?

Sorry about that, I guess I was trying too hard to avoid posting a duplicate bug. I will post a new bug report with sample files.
The .gif files linked to are no longer available. If this still happens please reopen with new links.
