Chrome Extensions for Web Design and Development

UPD: The list is now forkable on github.

Originally I’ve posted an article called “Chrome Extensions I can’t live without” a few months ago. Later on I kept updating it with more and more extensions that I found useful – mainly in the “webdev and design” category. Today I’m extending it again and moving this list to a separate article for flexibility and convenience. Here is the list of design/webdev only extensions that I use in the work process.
