About

This site is mostly about my work as a developer on Firefox and other projects. The easiest way to get in touch is to email briangrinstead@gmail.com. Also, as bgrins on github, linkedin, matrix.

Here's a blurb about me:

Brian Grinstead is a senior principal engineer at Mozilla working on Firefox and the web platform. He joined Mozilla as a web developer in 2013 to help launch Firefox DevTools, and has worked on thousands of changes to the browser since, including shipping Developer Edition and leading a major refactor of the desktop UI. He's also helped to ship cross-browser performance benchmarks like Speedometer, and serves on the steering committee of the Alliance for Open Media.

And here are some projects from over the years:

Improving Performance in Firefox and Across the Web with Speedometer 3
XBL to Web Components migration in Firefox: posts tracking the refactor on firefox-dev from 2018-2020.

Various utilities: Browser-based diff tool, CSS Gradient Generator, Color scheme generator, Instant Sprite (CSS sprite generator), iOS UIColor Picker, test pages for DevTools features
