1914751 - Cannot Block Thunderbird's Animation

Status: RESOLVED FIXED

(Thunderbird :: Disability Access, defect)

Description

[MarjaE]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:129.0) Gecko/20100101 Firefox/129.0

Steps to reproduce:

Open "Display the Thunderbird Menu" (in Linux, it's in the upper right corner, but exceedingly hard to see; in MacOS, it's next to the search bar) and click "New Account" (in Linux) or "New" (in MacOS).

Actual results:

The new menu options animate sliding left. If I close the options, something animates sliding right.

I've configured both systems to reduce animation. (In Linux, I'm using Cinnamon, which has Preferences > Effects > Desktop and Window Effects, but other desktops have their own settings so a Thunderbird setting might work better; in MacOS, I'm using Reduce Motion).

I've also searched for preferences or config preferences to reduce motion, but they don't seem to exist).

Expected results:

Thunderbird should have ui.prefersReducedMotion, like Firefox, and this option should de-animate these menus.

Thunderbird on MacOS could detect Reduce Motion settings.

Thunderbird on Linux probably couldn't rely on desktop or system settings, because Cinnamon, Gnome, KDE, etc. have different and sometimes incompatible settings.

Thunderbird on Linux could use an easier-to-see menu button too.

Thunderbird does have layout.frame_rate, and a low setting can de-animate things. I often use 1/second in Firefox, but would rather not rely on it in Thunderbird.
