Quais são alguns dos melhores aplicativos ou extensões disponíveis na Chrome Web Store para programadores e desenvolvedores de páginas web?

Following are the plugins that I find useful for my work.

JetBrains IDE Support

HTML/CSS/JavaScript editing and JavaScript debugging using JetBrains IDEs.

With the JetBrains IDE Support extension for Google Chrome you can debug JavaScript code in Chrome from WebStorm, PhpStorm, IntelliJ IDEA Ultimate, PyCharm Professional, and RubyMine. Além disso, você pode ver as mudanças que faz em arquivos HTML ou CSS no navegador imediatamente, sem recarregar a página, graças ao plugin Live Edit.

ColorPick Eyedropper

Uma ferramenta de conta-gotas e selecionador de cores que lhe permite selecionar valores de cores de páginas web.

Page Ruler

Draw a ruler to get pixel dimensions and positioning, and measure elements on any web page.

Stylish

Restyle the web with Stylish, a user styles manager. Stylish lets you easily install themes and skins for many popular sites.

EditThisCookie

EditThisCookie is a cookie manager. You can add, delete, edit, search, protect and block cookies!

There are many more but just to get me around the day and reading and storing links.

Will update more as I find.
