hw3: uses for firebug

So, I've been using firebug for a while, since I like doing web stuff. For HW3, I think the most important feature of firebug is that it can help you debug your javascript, it basically turns red and shows you how many errors there are in your script code.

You can also use firebug to change your css on the fly, so you can see how it'll be visually interpreted, so that you know what changes you should make on the hard copy.

Moreover, it will show you GET and POST information (which you need for Ajax) to verify that you're correctly sending or receiving your information from the server. It can also show you the header (which can be pretty important if it holds the information that the server can parse and handle on the server side). And finally it also shows you the amount of time it takes to load an image or retrieve your code. You are planning on optimizing, you can use this information to consider certain cut backs in your code, you could create smaller images, or images that are more likely to compress better.
