rendering problems with new website in FF on osx

[JoernT]

With FF 30.0 on OSX the new site is not rendered correctly in some places. As it's hard to describe i attached a screenshot.

Furthermore in the new section about material design also not all of the controls (namely dialog and toast) are not working on FF (nothing is displayed).

Same problem with FF 30.0 on Windows 7.
