Megabar expanding/shrinking issue and epilepsy

Emotional, Burning, Unlimited Tuned Laboratory

Steps to reproduce:
update to the new Firefox 75 version
use the address bar

Actual results:
the expanding and shrinking of the address bar has caused triggers with my epilepsy. the sudden expanding and then when moving away from the address bar has a similar effect as a strobe light and has triggerd mild symptoms of epilepsy such as losing focus, feeling mildly dizzy, and eye studdering (eye movements like little jerks)

I want to make a point that these are mild reaction and although I don’t end up on the floor having an epileptic seizure, the effects to cause stress and triggers which could lead to that end result …

Expected results:
Disabling the new function the issues cease to happen.
