If you're like me, you've learned everything you know about programming or designing web sites from on-line resources (and maybe a few books or CHM & PDF's here and there). This isn't any new news, but there are a lot of really nice resources out there, created by developers to help us to quickly reference those on-line resources that we so often use.
The only one about which I can make a testimonial is Rijk's Panelizer, and I must say that it's a very nice little ditty. Use the "Panelizer" to "install" LOCAL versions of CSS, HTML, JavaScript, DOM tools, etc (you should ensure that you first have a "Panels" bookmark folder/ option), and they open in Firefox's side panel (they were originally designed for Opera, so it works there too of course).
i hope someone can make use of this.
enjoy!
