Keith Curreri - Blog Headshot

By Keith Curreri on March 02, 2011

This is my first post in a series of posts on the Web Developer Toolbar. There are many features in the toolbar that make a web developer’s life so much easier. In this series I will go through each of the sections and show in detail what each tool does. Some tools are more useful than others and some you may only use rarely, but you may not know which ones to use until you see what the toolbar can do.

This first post in the series will cover the basics and show you how to install it. Then each subsequent post will go through each of the categories.

Okay, I’ll have to read more as you go along because, truthfully, I don’t get it still.

This post is sort of my introduction to the series, hopefully by the end everything will be more clear. I think that as the series progresses, I will have to go back to previous articles in the series and clear them up some. I can see how this first post it a bit cloudy.

The web developer toolbar is pretty complex and this series will have a lot of information, unfortunately the next few posts may add to the confusion until I can get into the meat of the features…

Would love your thoughts, please comment.x
