worst add on

Literally does nothing Bewertet mit 1 von 5 Sternen

This plugin must have been killed off a while back. It literally does nothing after you install it. There isn't even a button to click to run the plugin.

Stopped working.

Furthermore, it will need to be moved into Firefox DevTools instead of Firebug

Enter this url in FF about:addons.
Then click on YSlow Prefencies and check first checkbox. Then, when u'll reload u page, it would work!

Worst Experience Ever Bewertet mit 1 von 5 Sternen

This addon is a total waste of time. Not only is this useless because when you finally get to access it - clicking on the "Run Test" doesnt respond, it also irritates you while installing it and figuring out where to find it - ie, inside firebug!

Complete and Utter waste of time ever.

This used to be a great addon but has not worked in a very long time. Mozilla should just pull it off the site already.

It mostly works for me in FF 46.02! Bewertet mit 4 von 5 Sternen

In Firefox, go to Add-ons, then Extensions, then see Yslow. Click options and click "Automatically run YSlow when page finishes loading." It will give the overall rating plus the element ratings, but the elements themselves are still not clickable. Great insight anyway.

YSlow Workaround! Bewertet mit 1 von 5 Sternen

It's clear from this very long thread YSlow isn't working anymore with current FF versions. However there's hope!

These three sites will give the web page speed info desired and more: gtmetrix.com | host-tracker.com | webpagetest.org

gtmetrix.com has both PageSpeed and YSlow operating.
