Unable to Pan/Zoom for 3.5 JS API

[SunilPalkar]

Hello all,

I am having few maps built in version 3.5 . I found that I can not drag/zoom in/zoom out the map. Map works with Google Chrome but not in Firefox (v. 29.0 & 29.0.1)

-Attached sample code in JSFiddle
-Tried same version using locally and online references..
-Not able to identify the problem (browser issue , JSAPI issue?)
-Last week it was working fine.

Any help will be great !!!

thanks in advance : )
