1768787 - Add an option to disable all easing function animations

Status: NEW

(Core :: CSS Parsing and Computation, defect)

Description

[MarjaE]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

A lot of sites use "ease-in-out" or similar "ease" settings for css animations. These cause motion sickness and migraines.

Migraine warning both for the now-standard layout, and for the test sections here:

https://developer.mozilla.org/en-US/docs/Web/CSS/transition

Actual results:

A number of Firefox bugs, such as bug 1764126, would add further support for ease animations.

Expected results:

It'd be helpful to let users block all ease animations.

I haven't been able to bibisect, because Mozregression crashes.

Migraine warning for standard layout here, but this indicates the bug was introduced in Firefox 4:

The Bugbug bot thinks this bug should belong to the 'Core::CSS Parsing and Computation' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

MarjaE, are you suggesting an option to disable easing timing function animations as part of bug 1725474?
