Hi,

I am not able to open Hello world application in Firefox 7.0.1. I am developing this app using this http://docs.sencha.com/ext-js/4-0/#!/guide/getting_started
tutorial from Sencha documentation.When I opened Firefox Web Developer Console, I found following CSS errors :

Unknown property 'box-sizing'.  Declaration dropped. @ http://localhost:8080/ExtJs/HelloWorld/extjs/resources/css/ext-all.css:1

I would like to know why these many errors are coming and how to resolve these errors?

Just looks like FireFox doesn't like a lot of the CSS. Is it impacting the actual usage of the app?

@Mitchell Simoens,
Thanks for your answer. I am new bie to Javascript world and what I am trying to do is create one 'Hello World' application and that app is also is not working correctly. According to tutorial which is on Sencha web site, this sample app is supposed to show some panel and message on it.
So I want to know whether its fault int Sencha itself or I am missing anything? Is it common to have so many css errors?
