I have two weapons I use when creating my webpages. I use these Firefox plugins primarily to make sure my pages load lightning fast.
Web Developer – I use it mostly as an easy way to inspect my pages (as well as pages of others.) It is also an easy way to tweak and test your css code.
Firebug – I love this one for a single feature it has. Install it and check out the “Net” tab. It will show you all of the items loaded when you visit a page. It will also tell you the load time for each item as well as for the entire page.
Take a moment and install them. You’ll need them for my next post on how to tweak your webserver or php code to serve up your pages lightning fast.
