<p><strong>TLDR:</strong> Firefox 151 is adding server location selection to its built-in free VPN, fixing the biggest complaint since launch. A detailed walkthrough of Cloudflare’s ecosystem makes a credible case for it as a coherent full-stack platform rather than a grab-bag of services. On the tooling side, JetBrains shipped a ReSharper extension for VS Code that finally makes C# work viable outside Rider. A few smaller but useful things landed too: a canvas accessibility proposal is now behind a Chrome flag, and a pattern guide for keeping AI agents from gaming their own tests.</p>

<h2>Firefox 151 adds server location selection to its free VPN</h2>
<p>The built-in VPN shipped in Firefox 149 with no way to pick your server — it just routed you to the nearest Fastly proxy and called it a day. Firefox 151, due May 19, fixes that with a manual country picker covering the US, UK, France, Canada, and Germany. The VPN still requires a Mozilla account, caps at 50 GB/month, and only covers in-browser traffic. Android support with the same feature set is also planned.</p>
<h2>Cloudflare as a full-stack platform, honestly assessed</h2>
<p>A post making the rounds walks through Cloudflare’s service ladder — Pages/Workers, then bindings, then D1/R2/KV, Durable Objects, Workers AI, Queues, Hyperdrive — and the argument is more coherent than the usual vendor pitch. The core observation is that each layer is designed to solve the exact pain introduced by the previous one. The author doesn’t skip the downsides: real vendor lock-in, a JS/TS-only runtime, and uneven maturity across services. Worth reading if you’re evaluating it seriously.</p>
<h2>ReSharper lands in VS Code for .NET work</h2>
<p>JetBrains shipped an official ReSharper extension for VS Code in March 2026. A Rider-primary developer walked through what it actually adds over the Microsoft C# Dev Kit: deep refactorings like Extract Interface and Move Type to File, assembly decompilation for NuGet navigation, a proper Solution Explorer, live templates, and runtime-safety inspections. Setup requires disabling C# Dev Kit to avoid conflicts. The author isn’t switching from Rider but calls it a capable fallback for borrowed laptops, Linux machines, and SSH sessions.</p>
<h2>Canvas accessibility gets a real proposal</h2>
<p>Canvas-based 3D experiences are almost universally inaccessible because developers skip semantic fallback content. The HTML-in-canvas proposal from WICG aims to fix this by automatically syncing visual canvas rendering with semantic HTML, so you’re not manually maintaining two parallel representations. It’s available now behind a Chrome/Brave flag (<code>chrome://flags/#canvas-draw-element</code>). Early days, but this is the right approach — accessibility built into the rendering pipeline rather than bolted on afterward.</p>

Web Digest

Firefox 151 (due May 19) adds manual country selection to its built-in free VPN, covering US, UK, France, Canada, and Germany — fixing the biggest complaint since launch. A thorough walkthrough of Cloudflare's service stack argues it forms a coherent full-stack platform, while honestly noting vendor lock-in and JS/TS-only constraints. JetBrains shipped an official ReSharper extension for VS Code, bringing deep C# refactorings and Solution Explorer to developers outside Rider. Other highlights include a Chrome-flagged HTML-in-canvas accessibility proposal, TypeScript patterns for preventing AI agents from gaming their own tests, a SKILL.md collection for tuning AI frontend codegen tools, Bun's parallel compilation improvements, and a tRPC guide as an Apollo Federation alternative.
