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. :(

YSlow 2.0.5 crashes Firefox 3.5. YSlow 2.0.4 causes problems with extension DownloadThemAll, and maybe other extensions too.

DO NOT INSTALL!

I've switched to the open source Google Page Speed:

Can break some web sites that use AJAX, so not an option for me (unfortunately).

I found a small bug: when I install this add-on on OSX the bottom of Firefox Preferences window is cut off, so some of the controls aren't accessible.

Anyway that's a really great utility!!!

So-so. Big drawback - they've destroyed the functionality of smushit, the once wonderful image optimisation tool. What a shame the original tool isn't still available separately for web developers.

Nice testing tool ... but only turn it on when testing load speeds. It will cause Firefox to double submit any form data creating multiple entries in web databases or apps you run if it is enabled. Be sure and turn it off when not testing to avoid this problem. You might also find that a double submit will also cause the page to load slower ... doh! The test info is accurate since it measures the first load then reload the page for display.

Sehr nützlich, um die eigene Webseiten zu testen. Die Grafiken könnten etwas schöner sein.
