- Rated 5 out of 5哈
- Rated 1 out of 5worst add on
- Rated 1 out of 5This 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.
- Rated 1 out of 5Stopped working.
Furthermore, it will need to be moved into Firefox DevTools instead of Firebug - Rated 1 out of 5Its not working in firefox 50.
- Rated 1 out of 5stupid add-on. does not install.
- Rated 1 out of 5does not work in v51 nightly.
- Rated 1 out of 5Do`nt work in FF48
- Rated 5 out of 5Enter 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! - Rated 1 out of 5In FF 47
- Rated 1 out of 5This 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. - Rated 1 out of 5This used to be a great addon but has not worked in a very long time. Mozilla should just pull it off the site already.

- Rated 4 out of 5In 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.

- Rated 1 out of 5It'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. - Rated 1 out of 5Just installed Yslow. I think. Where can I find it? Where can I click on something to see something? I don't understand. There is no status bar so there is no Yslow icon. If I hit F12 I don't see Yslow anywhere. Am I missing something? Do I have to use Chrome from now on, which I don't want?
- Rated 1 out of 5To force users to switch from Firefox to Chrome. Seek for alternatives.
- Rated 1 out of 5I just install it but not working correctly . What can i do for this ?????????
