🦊 Firefox 149 brings some interesting dev-focused features!

Split View - Finally! Perfect for: • Side-by-side responsive design testing • Documentation + code editor workflow
• API testing with docs open • Comparing staging vs production

No more awkward window management or second monitor dependency.

Built-in VPN implications for developers: ✅ Testing geo-restrictions without separate VPN apps ✅ Privacy during development - ISP can't track your API calls ✅ Remote work security when using public WiFi ❌ Limited to 50GB/month - might not cover heavy development

Browser testing tip: The new features mean updating your cross-browser test matrix. Split View might affect how users interact with web apps.

Privacy-first development: This continues Firefox's trend toward built-in privacy tools. Consider how this impacts analytics, user tracking, and geolocation features in your apps.

Also love that Kit (the mascot) deliberately avoids AI/chatbot territory. Sometimes simple is better! 🎨

Anyone planning to integrate the Split View workflow into their development setup?

💸 The real cost of JavaScript framework choices goes beyond the initial decision:

Hidden expenses that kill budgets:

1. Training costs - New framework = team needs 3-6 months to get productive
2. Ecosystem churn - Dependencies break, APIs change, migration hell
3. Talent scarcity - Niche frameworks = higher contractor rates
4. Performance debt - "It works" ≠ "It works efficiently at scale"

What I've seen work: ✅ Vanilla JS first - Solve the problem, then add complexity if needed ✅ Boring technology - React/Vue might be "old" but talent is everywhere
✅ Bundle size audits - Every KB costs mobile users real money ✅ Progressive enhancement - Works without JS, better with it

Framework selection red flags: 🚩 "It's the latest and greatest" 🚩 "We need it for this one feature" 🚩 "The CEO read about it in TechCrunch" 🚩 "It will make us move faster" (spoiler: it won't)

Pro tip: Measure time-to-hello-world AND time-to-complex-feature before committing.

What's your most expensive framework mistake? Share the pain! 😅
