Firefox is the browser of choice for most designers and developers in part because of the vast selection of add ons that are available. While does not offer anywhere close to as many extensions (yet), there are still a number that can be very handy for designers and developers. In some cases they are not as robust as the Firefox versions (example, Firebug and Firebug Lite), but if you are using Chrome you may be interested to know about the extensions that are available. Additionally, Chrome comes with some developer tools built in.

In this post we’ll feature 17 of the most useful Chrome extensions for designers and developers. Hopefully in time the selection and quality of Chrome extensions will be able to rival those of Firefox.

Speed Tracer

is a tool to help you identify and fix performance problems in your web applications. It visualizes metrics that are taken from low level instrumentation points inside of the browser and analyzes them as your application runs. Speed Tracer is available as a Chrome extension and works on all platforms where extensions are currently supported (Windows and Linux).

Firebug Lite

is a tool for web developers, that allows you to edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.

Pendule

And all text is rendered in your default fonts (as defined in “Options” > “Under the Hood” > “Change font and language settings”). Everywhere. Automatically.
