Key Differences

Chromium is a free and open-source web browser project from which Google Chrome draws its source code, while Firefox is a popular web browser created by Mozilla, a non-profit organization with a strong emphasis on privacy and user freedom.
The Chromium project is often seen as a bleeding-edge version of Chrome, providing the latest features but it's less stable, whereas Firefox prioritizes a balance between features, speed, and user privacy, often releasing new functions after thorough testing.
Regarding extensions and themes, Chromium supports a wide range, especially those available in the Chrome Web Store, while Firefox, known for its customizable interface, supports a variety of add-ons through its own Firefox Add-ons Manager.
In terms of privacy, Chromium has stirred some concerns due to its ties with Google services and data collection practices; in contrast, Firefox is acclaimed for its user-centric privacy approach, offering robust protection against tracking and data collection.
Both Chromium and Firefox are available across multiple platforms, but while Chromium often requires manual installation or is bundled with third-party applications, Firefox provides straightforward, direct downloads for its browser on various operating systems.
