Disable Animations автор Vuccala

Gets rid of the annoying UI animations that are the visual scourge of today's internet. Stops the annoying fading, sliding, bouncing, spinning and twirling.

The drop-down panel offer 8 different animation-disabling options, 7 of which are enabled by default. You can manually disable them (and your choice is remembered on a per-site basis) in cases when a certain animation-disabling option breaks a site.
