Umm the Chrome extension states it can access: "All data on your computer and the websites you visit".

Say what?

This suggestion from Google especially looks fun: The following publicly cacheable, compressible resources should have a "Vary: Accept-Encoding" header: * http://www.google.com/buzz/api/button.js However, it's a useful tool. It gives me useful suggestions for improving. Anybody knows a simple tool to minify javascript?

It's very common. It's a limitation/feature of the Chrome API. If you want to make an extension that can be run on any page, this warning will appear.

I often use the Closure Compiler at http://closure-compiler.appspot.com/ (online) and http://code.google.com/closure/compiler/ (offline)

This is nice, but I find it much less usable than GTMetrix: http://www.gtmetrix.com which runs both Google Page Speed and Yahoo YSlow.

As an added bonus, GTMetrix also shows you the resource loading timeline.

Nice tool, even if it makes some funny suggestions:

Minifying the following JavaScript resources could reduce their size by 1.1KiB (0% reduction). Minifying http://ajax.googleapis.com/.../jquery-ui.min.js could save 641B (0% reduction). Minifying http://ajax.googleapis.com/.../jquery.min.js could save 516B (0% reduction).

I just noticed that your screenshot isn't even of Page Speed. It is of the Audits tab in Chrome Developers Tools.

It is not mine, but gautaml's one, and it use the independent tool of chrome that perform the same test. But when using the webservice it shows different results.
