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 [email protected]. Also, as bgrins on github, linkedin, matrix.

Here's a blurb about me:

Brian Grinstead is a senior principal engineer at Mozilla, where he works on improving the web alongside engineering teams at Mozilla and with colleagues across the industry. He joined Mozilla as an experienced 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 Firefox UI. He's recently been focused on web performance: working together with all major browsers to ship the Speedometer 3 benchmark.

And here are some projects from over the years:
