There are lots of firefox addons for web development; here are the best firefox addons for web development I use on a daily basis.
firebug
Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page
Thanks for the list. One other tool I use all the time is ShowIP. It just shows the IP of the site you’re connected to at the bottom of the page.
Useful if you’re moving/testing sites between different servers or build to live environment. Especially if you’ve updated your hosts/resolve.conf file for testing.
yeah, one of the developers at work uses that too =) its pretty decent
ive also subscribed to your feed cos i like the content on your site =)
Thanks Jonathan and thanks for your comments on mysql and concat. Very useful!
