Javascript, firefox, and ASP.NET MVC 3 development

I am currently part of a development team extending functionality of ASP.NET MVC project allowing users to review data reports.  

The cool parts of this job are: 

• MVC from 1.1 to 3.0 in this version
• Getting to move up to VS 2010.  (before anyone comments I know I want VS 2012 and MVC4) 
• Learning the ends and outs of a complex web site/service by analyzing extending code.  (So much better than the 'Hello World' using .net).
• Being able to leverage by SQL and C# knowledge so I'm not completely dead weight until I become proficient in javascript.

Things I learned so far:

• Javascript, are you kidding?  This is why smart device development is such a good idea.  Gets away from a rather poor scripting language. 
• I hate using FireFox but I love it for debugging.  It is too bad the rapid release process has destroyed one of my favorite browsers.  
• Browsers I'm currently concerned with supporting: IE9/IE10, Chrome, and Safari.  
• Two things I love about Javascript: debugger and alert().  The rest can go away.
• The joy of getting a html button wired to a javascript function to hit Controller.Action()
• Much deeper understanding and appreciation for large sites as Google and Facebook.
• http://stackoverflow.com/  is still my best friend!
