This is a nifty little tool to add to your web development toolkit! Yahoo has developed a nifty website speed analysis Firebug extension. Yep. Not Firefox…FireBug. (Which I guess makes it a Firefox extension with a dependancy…but whatever). The extension is YSlow which Yahoo! describes as:
YSlow analyzes web pages and tells you why they’re slow based on the rules for high performance web sites. YSlow is a Firefox add-on integrated with the popular Firebug web development tool. YSlow gives you:
Install Firebug first!
- Performance report card
- HTTP/HTML summary
- List of components in the page
- Tools including JSLint
Once installed, the plugin adds its features onto Firebug itself, giving a few extra things to click on and view. (Note the added menu options at the top of the following image):
If you are curious about what to do with the data that YSlow provides, Yahoo has some nice docs as usual. Overall, this is a sexy little tool!
