Mozilla Firefox is an open-source web browser developed by the Mozilla Foundation.

Since its first major release in 2004, it has stood out on the browser landscape for its emphasis on privacy, security, and customization.

Brian Grinstead is a senior principal engineer at Mozilla.

He joins the podcast with Kevin Ball to talk about the Firefox architecture, the recent UI Refactor,

web performance, the role of Rust in the browser, and more.

Kevin Ball, or K. Ball, is the vice president of engineering at Mento and an independent

coach for engineers and engineering leaders. He co-founded and served as CTO for two companies,

founded the San Diego JavaScript meetup,

and organizes the AI inaction discussion group through latent space.

Thank you. Brian, welcome to the show.

Thanks for having me.

Yeah, no, I'm excited.

Let's maybe start out a little bit.

Can you introduce yourself to our listeners and share a little bit about what you do? For sure. My name is Brian Grinstead. I'm a senior principal engineer at Mozilla working on Firefox and the web platform. I've worn a bunch of hats at Mozilla since I joined in
