Grid Scrollbar problem with Firefox

If I scroll in a Grid in Firefox the scrollspeed is really slow. It seems wired but i hope i get some help.

I don’t think this is only for firefox, this depends what kind of content you try to rendering and how you did that.

Hi, thanks for your time.
But this would not explain why the Vaadin Grid Sample´s in Firefox are slow aswell.

I’m experiencing the same problem.
Scrolling works fine in all browsers but firefox. For the same content it is really very slow in firefox, even the demo for grids on this page has the same issue.
