I'm using MacOS 10.14. I can't update further. I am gradually setting up Fedora Linux with Cinnamon.

Thunderbird is 115/2.0.

is this the search of addons.thunderbird.net inside Thunderbird?

Yes.

If I reach this in Thunderbird... https://addons.thunderbird.net/en-US/thunderbird/addon/a-solid-green-success/?src=search

There are 2 images inder "Add to Thunderbird" which animate on mouseover. (And give me another @#% migraine.) I can't inspect them within Thunderbird. If I inspect them in Firefox, it appears to depend on https://addons.thunderbird.net/static/css/zamboni/impala-min.css?build=87ffc96 and in particular ".previews li a" in lines 4286 and after.

What happened?

Animations occurred when the user's settings are set to reduce motion.

What did you expect to happen?

Reduced motion with animations.

Anything else we should know?
