I built a browser extension that stops animated images such as GIFs by default.
I've always found it annoying that browsers autoplay animated images, and there still isn't a built-in way to control that behavior.
The extension shows the first frame and adds a play/stop button directly on the image.
What started as a personal utility ended up being published on the Firefox and Chrome extension stores. It's still a small project, but it solved a problem I had every day.

Bug reports and feedback are very welcome.
Disclaimer: I previously posted a Show HN about it, but it didn't get traction [1].
