Below is a list of Chrome extensions that I've found to be especially helpful for software development. There's a section for Chrome Extensions by Google, and another section for Chrome Extensions for GitHub.
- Clear Cache - A simple extension that clears your browser cache (and optionally history, cookies, etc) with a single click. I use this extension multiple times per day.
- Library Sniffer - Identifies the technologies running any web page.
- WhatRuns - Same thing as Library Sniffer, but somehow picks up on a completely different list of technologies.
- Window Resizer - Emulate other devices/platforms by quickly resizing your screen. Chrome Dev Tools offers this functionality too, but this exension can sometimes be a quicker alternative.

- WhatFont - The font equivalent to Colorpicker, this extension allows you to easily identify any font on any webpage simply by hovering over it.
