animated gifs on firefox

Firefox won’t show animated gifs when using opensuse but does show them on other distributions. Do I need to add something to opensuse?

I am seeing animated gifs on firefox (with Leap 15.1).

When asking about a problem,
Best to include a link to the example,
In this case a link either to the anigif or to the page with the anigif.



check the setting for “image.animation_mode” - it should be set to “normal” (Other options are “once” and “none”)

Here is what I get and the settings are already set to normal.
“We cannot play the video in this browser. Please try a different web browser.”

Are you using the packman repo?

If not, try (as root)

zypper ar -f  packman
zypper dup --from packman --allow-vendor-change

And check the multimedia guide:

(that’s for 15.0, but you can just change “15.0” to “15.1” wherever that string occurs).

Anigifs have nothing to do with multimedia.
Anigifs are a special type of gif image file which suggests to me a missing or incorrect MIME type.

Multimedia “video” is characterized by needing a codec to decode the video (type).

Where did this Firefox come from, the OSS or somewhere else?

I still don’t see that you’ve posted a link to the problem anigif, is it a downloaded file or can it be viewed online (If available online, others need to try to view using their own Firefox)


However, they also do not say “We cannot play the video in this browser. Please try a different web browser.”

So he really isn’t talking about animated gifs. He is talking about some kind of video, perhaps a video derived from an animated gif.

Yes, I agree…much more likely to be a codec issue at play based on OP’s posted information.

IMO not necessarily.
The browser might just not recognize the file and is making a best guess.

But, all of this shouldn’t be happening in a browser, period… AniGifs are common and should be recognized properly in the Browser, no troubleshooting should be necessary.

Is why I asked where the problem browser came from, if it’s an openSUSE problem or not.
Is also why I asked if there is a way anyone else can look at that file to see if the file displays in their browser or has a problem with it.


I have a screenshot but I can’t upload it here. It is happening on Twitter. There are two or three error messages.

You can upload a screenshot to and post the link here.

What version of Firefox are you using?

Okay, I pretty much guessed that. But I think those are short videos rather than animated gifs, though they may have been made from animated gifs.

I have installed here: chromium-ffmpeg-extra, chromium-plugin-widevinecdm – probably affect chromium but not firefox.

I also have libavcodec56, libavcodec57, libavcodec58 – all from the packman repo, and those probably do affect firefox. You can use the “versions” tab in Yast Software Management to see where your packages come from.

Although @jsawyer specifically mentions Twitter, it may be helpful to see what this page shows.

Don’t know if that helps. I also checked and saw that I have Version 67 on Ubuntu and 60.6.2esr here on opensuse.

Ok but each will see what their system reports not yours. In my case all the boxes are checked.

All the boxes were checked. I don’t know what happened but the problem is fixed.

It is good to hear that it is fixed, even if you are not sure how.
