Products that do what uBlock-Mv3 – Port of Full Manifest V2 uBlock Origin to Manifest V3 does

Ported this in an evening because the policy finally kicked the bucket in my Chrome install. It works reasonably well and I haven't found any issues with stability or importing external rules yet.

    Firefox 149 ships adblock-rust (Brave's Rust engine, MPL-2.0) completely disabled with no UI. It's controlled by two about:config prefs with no WebExtension API, so you can't touch them programmatically from a standard extension. This extension gives it a UI: ETP toggle (via browser.privacy API, instant), filter list manager with clipboard helpers for the manual about:config steps, and 8 preset lists. You can also add your own if you so desire.

    Hi HN, recently there have been a lot of discussions about Chrome's dominance on the Web leading to many websites being broken for alternative browsers. I think one of the reasons for this is that browser automation is hard and manual testing is often limited to the browser developers themselves use. I've distilled my best practices for browser test automation into the following project and hope it helps other developers to test their projects with more browsers: https://github.com/blueimp/wdio It's a Docker setup for WebdriverIO with automatic screenshots, image diffing…

    Hi HN, I've been building CH-UI, an open-source ClickHouse workspace. Today I'm releasing v2, which is a complete rewrite from scratch. v1 was a React SPA served via Docker. v2 is a single Go binary with an embedded Svelte frontend — download, run, open browser. No Docker, no Node, no runtime dependencies. What it does: - Multi-tab SQL editor with autocomplete - Database/table explorer with data preview - Saved queries - Tunnel architecture: run `ch-ui server` on one machine and `ch-ui connect` next to your ClickHouse — secure WebSocket tunnel, no VPN needed - Self-update (`ch-ui…

    Hey everyone, we built a local-first, open-source framework to allows you to export and build applications with your personal data. This August, we built a digital footprint exporter (https://news.ycombinator.com/item?id=41325719) that allowed people to get back their personal data, but there was no way to interact with it. So we added a python package, improved the reliability of the exporting, and implemented a unified JSON structure across platforms. How it works: - Electron’s built-in webview element is used to navigate to the platform’s website and the user can connect…

    Chrome recently shipped navigator.modelContext in Early Preview. It's a browser API that lets any website expose typed, callable tools to AI agents. I built webmcp-react because we wanted a simple way to add tools to our React app and figured others could benefit from it as well. You wrap your app in , call useMcpTool with a Zod schema, and that's it. Handles StrictMode, SSR, dynamic mount/unmount, and all of the React lifecycle. It also comes with a Chrome extension in the repo that acts as a bridge for MCP clients (Claude Code, Cursor, etc.), since they can't access…
