This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

Hey HN, I built uncurl.dev to scratch my own itch: I kept getting curl commands in API docs, bug reports, or Slack messages and wanted a quick way to visualize, run, and debug them without firing up Postman or writing code to dissect them. It was also sometimes painful to create a test page specifically for non-tech users to consume an API. I originally vibe-coded this over a weekend just to make it easier for myself to debug API requests shared as curl commands. It slowly grew into something I found surprisingly useful in my workflow, so I decided to clean it up and share it. uncurl.dev…

Sometimes you might want to share a screenshot of the website you're on, without revealing the personal data that is visible at that time. With Obfuscate, you can make text unreadable without changing the structure of the web page. Hit the extension button or press Alt+Shift+O to activate for the current page. (Note that extensions can't modify the add-on website, so trying it on there won't work.) Credit for the original idea: https://chaos.social/@maris/108379386421123630

Hi HN! I've been working lately on unifying firefox configuration. Many people work on creating custom `userChrome.css` files and modules, browser user scripts, etc, but it's hard to actually use these a lot of the time. It usually involves cloning a repo, finding a folder and lots of copy paste. My tool (firebuilder) has an interactive CLI to select what to apply, (e.g. firefox hardening, custom CSS, etc) then creates a brand new profile folder for you. You can also seamlessly port from an existing profile folder to preserve all of your history, bookmarks, extensions, etc. For those more…

OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…
