Javascript/IE ..... isssseee nooo woorrkkk ... heellp !!!

Hi .. as experienced .NET/WP7 developer, needing to get into mobile stuff. I thought I give JQM a shot. As an MS person (SM ?) , I chose VS2010 and IE9 to develop Javascript. It appears to be unworkable, for a number of reasons, of which the most important: 
 
1. IE keeps caching my programs, so I am unable to work with my latest development. (whatever i tell IE, it still keeps caching) 
 
 
 I was thinking of the combination Firefox/ Firebug. Does anybody have any experences/advice to give ???
