035 - AI Browsers, Chromium Monoculture, and the Future of Browser Security

This week on SysAdmin Weekly, Andy goes on a (fully justified) rant about the current state of browsers and why it feels like there are no good options left for sysadmins.

From Chromium monoculture and browser bloat, to AI creeping into the most trusted piece of software we use every day, this episode breaks down what’s changing, why it matters, and why “just turn it off” isn’t a real security strategy.

Along the way, Andy digs into:

• Firefox’s push toward becoming an “AI browser”

• Why agentic AI inside browsers introduces serious, unresolved threat models

• Real-world examples of prompt injection and AI-assisted data exfiltration

• Why browser forks are a stopgap, not a long-term escape hatch

• And the question: would a "boring" and "security-first" browser have a place in the market?

This is less about tools and more about trust, threat boundaries, and the slow erosion of choice in the browser ecosystem.

If you use a browser to manage infrastructure, security, or SaaS platforms (so… all of us), this one’s for you.
