    HTTP Switchboard for Chromium

    HTTP Switchboard for Chromium

    Point & click to forbid/allow any class of requests made by browser

    HTTP Switchboard is a Chromium-extension that lets users take very granular control over the kinds of requests their browser issued: cookies, scripts, images, frames, XHRs, etc., organized by source domain and destination domain, in a matrix interface. Instead of relying solely on curated blocker lists, this tool let you whitelist or blacklist entire classes of requests, per domain, with one-click operations at the intersection of type and domain. Its focus was on privacy and transparency: you could inspect attempted connections, block them entirely, and prevent data from leaving your browser at all. Although the project is now archived and succeeded by other tools (notably uBlock Origin and µMatrix), its design still influences modern request-filtering tools and is a historical reference in browser-privacy architecture. For users who want to understand how fine-grained control over web network activity can be exposed and managed, this repository remains instructive.

    HULL

    HULL

    Headless Shopify Starter – powered by Next.js + Sanity.io

    HULL is an open-source headless commerce starter template designed to help developers build modern Shopify storefronts using a decoupled architecture. The project combines a Next.js frontend with Shopify as the commerce backend and Sanity.io as a content management system, creating a flexible stack for building custom online stores. By separating the presentation layer from the commerce engine, HULL enables developers to design highly customized user experiences without being restricted by Shopify’s traditional theme system. The template includes integrations that synchronize product data from Shopify into Sanity, allowing developers and content editors to manage storefront content alongside product information. It also leverages modern frontend technologies such as React, Tailwind CSS, and static site generation techniques to improve performance and scalability.

    IPFS Companion

    IPFS Companion

    Browser extension that simplifies access to IPFS resources on the web

    IPFS Companion allows you to interact with your IPFS node and the extended IPFS network through your browser. The add-on is available for Brave, Chrome, Edge, Firefox, and Opera. It enables support for ipfs addresses, automatically loads websites and file paths from an IPFS gateway, allows you to easily import and share a file with IPFS, and more. IPFS Companion works in tandem with an IPFS node running on your local machine, so make sure you have a node installed before installing this add-on. The easiest way to install IPFS Companion is through your browser's add-on store. Make sure you have IPFS installed (opens new window)on your computer as well. Because IPFS Companion (in its standard configuration) talks to your computer's local IPFS node to work its browser magic, you'll need to have IPFS running on your computer, too.

    IPFS Web UI

    IPFS Web UI

    A frontend for an IPFS node

    A web interface to IPFS, shipped with Kubo, and ipfs-desktop. Check on your node stats, explore the IPLD powered merkle forest, see peers around the world and manage your files, without needing to touch the CLI. When working on the code, run an ipfs daemon, the local dev server, the unit tests, and the storybook component viewer and see the results of your changes as you save files. If you need to run IPFS in a Docker container, you can still have Web UI available by exposing both the Gateway and Web UI ports. The end-to-end tests (E2E) test the full app in a headless Chromium browser. They spawn real IPFS node for HTTP API and a static HTTP server to serve the app. The purpose of those tests is not being comprehensible, but act as a quick regression and integration suite.

    Image Toolbar

    Image Toolbar

    Provides easy access to common image functions in Mozilla Firefox.

    This is a near parallel fork of Cussers wonderful Mozilla Firefox Add-on Extension with a few tweaks. "Single-click access to common actions for images (e.g. saving, copying, printing). This extension is intended to provide a replacement for the equivalent toolbar in Internet Explorer." See upstream at https://addons.mozilla.org/firefox/addon/image-toolbar With any luck I hope to have it pulled as a RFE. Please note since Firefox (Fx) went to the mundane signing I am no longer publishing a Fx xpi... however it does work in SeaMonkey (SM).
