Ryan Boudreaux recommends some Chrome extensions that are especially useful for web developers.
Google Chrome is fast becoming the go-to browser worldwide, having surpassed Firefox in November 2011, and closing in on IE in May 2012, according to Global Stats StatCounter for global browser market share. It's also no secret that many of the users who have made the switch to Chrome are web developers, and this short list of extensions will allow you to integrate your browser with a number of web developer tools utilizing several unique methods.
Web Developer, by Chris Pederick, adds various web developer tools to the browser, including the ability to modify CSS, forms, information, images, outline, several validation tools, and resize.
PageRank Status shows Google Page Rank and Alexa Rank of current web page, quick access to Geo IP Location, Whois, Alexa, back links and indexed pages.
Color Picker, by Peter Dematté, is a light weight all around extension that can display and let you choose the entire color palette in HSB and RGB color modes. This highly customizable, easy to install, and speed-optimized app comes in four different sizes (from 151 x 87 pixels to 407 x 302 pixels), and therefore, different feature levels so you can use it for varied projects.
SEO for Chrome, by marketingabuse.com, is a developer tool extension and it provides easy access to Search Engine Optimization Tools that can help you with competitive analysis; keyword research; and pages indexed in Ask, Bing, Google, Yahoo, Baidu, and Yandex.

Edit This Cookie, by Francesco Capano, is a small, simple, and extremely useful extension that let's you perform anything you might actually need to do with cookies. This extension lets you delete all cookies in a page, delete only the chosen cookie on a page, edit any cookie, add a new cookie, search a cookie, protect a cookie (read-only), and block cookies using the cookie filter.
Proxy SwitchySharp, by meow, allows you to manage and switch between multiple proxies quickly & easily, and is based on "Proxy Switchy!" & "SwitchyPlus". It uses Chrome Proxy API instead of changing system proxy settings; supports auto switching, which switches among proxy profiles according to URL rules; allows data import and export; includes online rule lists which are AutoProxy Compatible; uses event handling instead of polling to monitor proxy change; and provides advanced quick switch mode options that allow you to switch among your proxies with one click.
