🦊 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! 😅

Good list. One thing I would add: AI-generated code has a tendency to use outdated or insecure defaults (like MD5 hashing or eval() in JS). Static analysis catches syntax-level issues but not logic flaws.

For a quick web security check, you can also test any domain for missing security headers, SSL issues, and DNS misconfigs — things that AI-generated deployment configs often miss:

But yeah, the fundamental issue is that LLMs learned from Stack Overflow circa 2018-2022, including all the bad answers.

Good call on ncdu. I use it all the time for finding what’s eating disk space. The interactive TUI is way faster than piping du through sort. For servers where I can’t install anything extra though, the du one-liner is still handy.

Thanks! I use a lot of these daily for quick checks. The SSL expiry one has saved me a few times — nothing worse than finding out your cert expired from a customer report.

I also have a cron that runs curl -s http://5.78.129.127/api/ssl/mydomain.com | jq '.days_remaining' and alerts me when it drops below 14 days.

This is really cool. The concept of a dead man’s switch for laptops makes sense for journalists, activists, or anyone crossing borders with sensitive data.

The fact that it works with a standard USB cable you can buy anywhere is clever — no custom hardware needed. And being in apt now lowers the barrier significantly.

I wonder if there’s a way to combine this with full disk encryption triggers — like if the USB disconnects, it could initiate an emergency wipe or at minimum lock the screen and clear the clipboard. The Qubes OS integration they mention sounds promising for that.

The concerning part is how vaguely “age assurance” is defined. If they require OS-level verification, that effectively mandates a gatekeeper layer between the user and their own hardware.

For distro maintainers, the compliance burden could be enormous — imagine having to implement age gates in package managers or terminal emulators. And what counts as an “app store”? Is flathub? Is apt?

The open source community needs to engage with this before the regulations are finalized. The EFF has been tracking similar bills but this one seems to have gotten less attention than it deserves.

This is great to see in apt. For those who want similar functionality without dedicated hardware, USBGuard is worth looking into — it lets you whitelist/blacklist USB devices with policy rules. Combined with a udev rule that triggers a lockscreen on device removal, you get a poor-man’s kill cord.

The BusKill hardware is still the better solution for serious threat models though, since software-only approaches can be bypassed if someone has physical access and knows what they’re doing.
