YSlow for Firebug
YSlow for Firebug is the latest must-have extension for Web developers working the bleeding edge. It’s primary purpose it to analyze your pages and tell you why they’re so slow (get it?: [Yahoo||whY]Slow), but it also has some other handy tricks up its sleeve. In one cool little tool, you get:
- a performance report card (based on the Yahoo! 13 Simple Rules for Speeding Up Your Web Site)
- an HTTP/HTML summary
- a list of components in the page
- other tools including JSLint
(Those with a keen eye may notice that YSlow is an extension for Firebug—which is itself a bad-ass Firefox extension.)
A really useful tool - looks like I have some work to do! What about the rest of you? I would love to hear what other webmasters think of these rules.
