Floorp: A Firefox-Based Browser for a More Flexible Web

Overview

Floorp is a Firefox-based desktop web browser developed independently of Mozilla. It offers an alternative for people who want to use the Firefox ecosystem while choosing a separate browser project and its own approach to the browser experience.

It is intended for everyday browsing across Windows, macOS, and Linux. The source repository also documents how to build the browser and where to find releases, documentation, and contribution guidance.

Key Features

• Based on Mozilla Firefox and the Gecko browser platform.
• Available for Windows, macOS, and Linux.
• Offers Windows installer and package-manager options, including winget and Scoop.
• Provides a macOS Universal build for x86_64 and ARM64, with Homebrew installation documented.
• Supports Linux distribution packages, Flatpak, and tarball downloads; some listed packages are unofficial.
• Includes an auto-update system for macOS, as described in the README.
• Uses the Mozilla Public License 2.0.

Use Cases

• Firefox users who want to try a separately developed browser based on Firefox.
• People looking for a desktop browser that runs across Windows, macOS, and Linux.
• Users who prefer installing software through tools such as winget, Homebrew, Flatpak, or Linux distribution packages.
• Developers who want to inspect or contribute to a Firefox-derived browser project.

Download a release from the Floorp website or the GitHub Releases page. For Windows, the README also documents winget install Ablaze.Floorp. See the README for platform requirements, other installation methods, and build instructions.

Alternatives

• helium: Helium is Chromium-based and emphasizes unbiased ad blocking, while Floorp is built on Firefox.
• donutbrowser: Donut Browser focuses on separate anti-detect profiles and per-profile proxies, unlike Floorp’s general-purpose Firefox-based browsing.

Considerations

Floorp is a Firefox derivative, not an independent browser engine, and the project states that it is not affiliated with Mozilla. Platform and architecture support differs: Windows requires x86_64, while macOS supports x86_64 and ARM64 and Linux lists x86_64 and AArch64. Some Linux packages are explicitly unofficial. The README points developers to a Deno-task-based build workflow and separate documentation for detailed build steps.
