Min
A fast, minimal browser that protects your privacy
Tabs in Min take up less space, giving you more room to browse the web. Pages you haven’t looked at in a while fade out, letting you see what’s important, and Focus Mode hides your other tabs to prevent you from getting distracted. See quick definitions and answers with information from DuckDuckGo, including Wikipedia entries and more. Jump to any site quickly with fuzzy search. Or search through the full text of every page you've visited, even if you don't remember the title. Tabs in Min open next to the current tab, so you’ll never lose your place. When you have too many tabs, you can easily split them into groups to help you stay organized. Min stops ads and trackers, so you can browse faster without being tracked. And when you’re using a slow or expensive internet connection, it lets you block scripts and images, so pages load faster and use less data. -

However, to translate, the contents of the web pages will be sent to Google or Yandex servers. You can also install via crx file, download the file using a download manager/or firefox. Activate developer mode and drag the file into the chromium extension manager. It doesn't work on Chrome/Edge. -

Lightpanda: the headless browser designed for AI and automation
Lightpanda is an open-source headless browser designed specifically for automation, artificial intelligence workflows, and large-scale web interaction tasks.

This design allows it to execute JavaScript and interact with web pages while avoiding the overhead associated with rendering images, fonts, and layout elements intended for visual display. The browser is implemented using the Zig programming language and integrates the V8 JavaScript engine to run modern web applications and scripts efficiently. Because it avoids graphical rendering and other heavy browser components, the system uses significantly less memory and launches almost instantly compared to conventional browsers such as Chrome. -

user.js
Firefox privacy, security and anti-tracking: a comprehensive user.js
A user.js is a configuration file that can control Firefox settings - for a more technical breakdown and explanation, you can read more in the wiki. The arkenfox user.js is a template that aims to provide as much privacy and enhanced security as possible and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen). Everyone, experts included, should at least read the wiki, as it contains important information regarding a few user.js settings. Note that we do not recommend connecting over Tor on Firefox. Use the Tor Browser if your threat model calls for it, or for accessing hidden services. Also be aware that the arkenfox user.js is made specifically for desktop Firefox. Using it as-is in other Gecko-based browsers can be counterproductive, especially in the Tor Browser. -

fx_cast
Chromecast Web Sender SDK implementation for Firefox
A Firefox extension that implements the Chromecast API and exposes it to web apps to enable cast support. Communication with receiver devices is handled by a companion application (bridge). Install the Firefox extension (from within Firefox) and bridge application via the installer packages. These are two separate downloads that can be found on the website or in the GitHub releases section. The bridge application is currently supported on Windows, macOS and Linux. Clicking on the toolbar button or Cast... menu item in the page context menu will open a popup that shows a list of receiver devices will allow you to start casting the currently detected app2 or media. The extension provides a whitelist for ensuring only trusted sites are allowed to load the cast API and communicate with receiver devices. Sites may be added to the whitelist, either by clicking one of the whitelist options in the toolbar button context menu whilst visiting the site. -

CanvasBlocker
A Firefox extension to protect from being fingerprinted
This add-on allows users to prevent websites from using some Javascript APIs to fingerprint them. Users can choose to block the APIs entirely on some or all websites (which may break some websites) or just block or fake its fingerprinting-friendly readout API. Canvas Blocker's default setting, and my favorite! All websites not on the white list or black list can use the protected APIs. But values obtained by the APIs are altered so that consistent fingerprinting is not possible. If a website is not listed on the white list or black list, the user will be asked if the website should be allowed to use the protected APIs each time they are called. Block the protected APIs only for websites on the black list. Ignore all lists and allow the protected APIs on all websites. -

BrowserOS
Agentic browser; privacy-first alternative to ChatGPT Atlas
BrowserOS is an open-source, agentic web browser built on a Chromium base that integrates AI agents directly into the browsing experience. Rather than just doing standard browsing, it places AI intelligence at the core: you can connect your own API keys (for e.g., OpenAI, Anthropic, Google Gemini) or run local models (via e.g., Ollama) so that your browsing data and automation stay on your machine — privacy and control are emphasized throughout. The interface remains familiar to users of Chrome (including support for Chrome extensions), but adds new capabilities: the browser can automate tasks for you, help you research by extracting and summarizing content, and enable agent-based workflows (e.g., “go fetch this info,” “fill this form,” “monitor this site”). The project is community-driven and entirely open source under the AGPL-3.0 license, which means you can inspect, fork, and contribute to the codebase. -

Stylus for Chrome
Stylus - Userstyles Manager
Stylus is a fork of Stylish for Chrome, also compatible with Firefox as a WebExtension. "Stylus" is a fork of the popular Stylish extension which can be used to restyle the web. Not "ish", but "us", as in "us" the actual users. Stylus is a fork of Stylish that is based on the source code of version 1.5.2, which was the most up-to-date version before the original developer stopped working on the project. The objective in creating Stylus was to remove any and all analytics, and return to a more user-friendly UI. We recognize that the ability to transfer your database from Stylish is important, so this is the one and only feature we've implemented from the new version. Two different optional code validators with user-configurable rules: CSSLint and Stylelint. Both validators use Web Worker API to run in a separate background thread inside the editor tab without blocking your interaction with the code.
