I'm using chrome to develop an ExtJS application. Today I tried to open my app in Firefox 10.0.2 and it doesn't even start up.

I keep getting this Error Message:

c is not a constructor | ext-debug.js (Line 6662)

I'm not sure where to start to get rid of this issue.

That happens when a file that it needs is missing. It's a very generic message, check you have all the files needed via .Requires in your code.

It's caught me out before where I had the right files, but they weren't loading in the order they were being called.
