Running it with Firebug 1.7x0b1 beta under Firefox 4. I cannot run a Yslow test using the "run test" button now. Firebug works well though. Perhaps a bug that still needs to be ironed out? Hope it will work soon as I love Yslow and use it a lot.

Due to the fact that Google now uses page-load speeds as a ranking factor; this is a critical plug-in that any SEO web-master needs to have installed in their browser. It gives high quality information that cant be overlooked.

YSlow is a usefull add-on especially for bigger sites. Used in combination with Googles Page Speed, webmasters have two very powerfull tools for analyzing websites. Even google suggests to use YSlow for web page analysis.

We integrated YSlow into our release cycle. QA opens a show stopper bug, each time our grade goes down...

YSlow 2.0.5 rendered FF3.6 (Vista, 32-bit) unusable - after more than 10 crashes, I disabled it. It looks like the YSlow 2.0.6 update today fixed the problem.

There were about 5-6 updates (1 per day) that all kept breaking and failing to fix the previous bug. Don't Yahoo test these things? 2.05 wouldn't even install!! Today's 2nd update seems to work so far. Fingers crossed.

Annoyed at all the errors and poor QA, but it is still a nice plugin when it works.

This is a great product with excellent utility. Good turn around on fixing the crashing error.

I look forward to more quality updates in the future.

Unstable Rated 2 out of 5 stars

It used to be a good addon, but recent updates show that testing is no longer done before releasing a new version. Now each update is worse than the one before. :(
