Is this intended? can it be disabled properly system wide?
Hate animations as they are distracting to my work flow .

I'm unable to reproduce this bug. I opened 10 tabs and was able to drag the 10th tab to the 2nd position and I could see both an animation of the tab moving in to place as well as the tab remaining in the 2nd position. I was able to see this work with the toolkit.cosmeticAnimations.enabled pref set to true, as well as set to false (after fixing bug 1366060).
