PR reporting plugin for chrome/firefox

I primarily use Chrome because it loads faster than Firefox (for me) and because of the inspect element option.

Does anyone know of a toolbar/plugin for Chrome that reports a site's PR (and maybe extras like alexa rank, etc.)?

I've tried searching for one but I don't seem to see any clear cut "best" plugins, and I'm a bit nervous downloading one from a non-trusted source.

Or one for Firefox, but I'd prefer Chrome.

you could try seoquake plugin, it has some nice features and you can use it in chrome
