Firefox - 1920x1080 Animated BTTV Emotes not looping correctly about the-ffz-addon-pack

That is default Firefox behavior.
It restarts all GIFs so they're in sync and the browser has to render them only once for performance reasons.

Nothing I can do about it - I'm also unsure whether or not there is a setting in Firefox to change that 🤔

I have found the issue.
So I have 3 monitors 4k, 2k and 1080p ...

It only fails to behave correctly on my 1080p one ... Because of windows ui scaling !!
My other two monitors use 125% and 175% - The 1080p one uses 100%.

So I switched to 125% on the 1080p one and .. it worked.

• Switching any of my other two to 100% also gives me the same issue.
  The only question now is why it wont run properly on 100%

Funny enough if I use 100% windows scaling and just increase the ui text through firefox -> Ctrl&Scroll it also starts looping correctly.

Demonstration: (I used CTRL&Mousewheel to zoom in through FF)

Doesn't change the fact that it's a Firefox issue and I can't fix anything about it.

If you use an actual BTTV browser extension instead of FFZ addon, animation in GIF emotes does not restart and it loops properly when new messages appear with same emotes. How come this Firefox behavior does not affect BTTV extension?

[Lordmau5]

Looking through their code I can't spot anything obvious that FFZ would be doing different.
They're both simply using an <img> element and.. nothing special besides that.

@Lordmau5 I think omitting srcset 1x could be the solution - and the reason why it is looping correctly with the bttv addon.
