I have already written about Firefox and that I use it as my primary browser. Actually I use other browsers only when testing pages I develop.
One of the biggest advantages of Firefox are its
extensions.
Those days I am working on XmlHttpRequest with JavaScript (also known as AJAX technology).
By viewing the source of the page - you can see the
initial source of the page, but there is no way to see what is the
current source of the page - the one generated by javascript. at least I thought so

I asked for some help on
dizajnzona forums and I received one very valuable suggestion from user
ivanhoe: "install
View rendered source extension".
And now I recommend it to all of you who work wiht DHTML: "install
View rendered source extension"
