YSlow 0.9.5b1 Release - Addressing Firefox and Firebug Compatibility

Committed to keeping up with the latest in Firefox and Firebug development, we’re happy to announce that a new version increment of YSlow was released, mainly aiming at addressing compatibility. What’s in this release?

Firefox 3 beta 5 support
Support for the latest versions of the different Firebug branches
Pie chart representation of the components in the Stats tab
Improved display in the expanded CSS expressions rule report in the Performance tab
Support for disabled Firebug Net Panel (default behavior in Firebug 1.2)
Misc fixes for the reports in the Tools section

Looking at the diversity of Firefox/Firebug versions, these are the current available branches for Firefox and Firebug.

Firefox has two active branches:

Firefox 2 - the current version is 2.0.0.14, this is the stable production version
Firefox 3 - the latest is 3.0. beta 5

Firebug has 3 active branches:

Firebug 1 – the latest version being 1.05, this is the stable version
Firebug 1.1 – the latest is 1.1.0 beta 12
Firebug 1.2 – the latest 1.2.0 alpha 21

Firebug 1 doesn’t work with Firefox 3, so there are a total of 5 combinations and the YSlow 0.9.5b1 has been successfully tested on all of them:

	Firebug 1	Firebug 1.1	Firebug 1.2
Firefox 2	Yes	Yes	Yes
Firefox 3	N/A	Yes	Yes

You can download the tool here, report bugs here, read the performance rules, and participate in the performance mailing list discussions. Also make sure you keep an eye on our performance-related postings on YDN and YUI Blog.

Enjoy,

Yahoo! Exceptional Performance

Any update for Firefox 3.0RC1?

Can you update YSlow for FireBug 1.2b1? YSlow stopped working with 1.2 at about 1.2A23. Thanks.

I'm running Windows XP SP2, Firefox 3RC1, FireBug 1.1.0b12 and when I attempt to install the YSlow 0.9.5b1 add-on it reports that FireFox 3 is not supported.

The version that supports FF3RC1 and Firebug 1.2 betas is under way, currently YSlow only supports FF3 betas and FB1.2 alphas.

It would be nice to have access to beta versions of YSlow. That way we can help with testing and get YSlow before its ready. Really wanting YSlow on RC1. :-)

Keep up the AWESOME!! work.
