About Firefox Nightly

Get a sneak peek at our next-generation web browser, and help us make it the best browser it can be: try Firefox Nightly. Nightly is an unstable testing and development platform. By default, Nightly sends data to Mozilla, and sometimes our partners, to help us handle problems and try ideas. Firefox Nightly gets updated every day and as a consequence, the release notes for the Nightly channel are updated continuously to reflect features that have reached sufficient maturity to benefit from community feedback and bug reports. Allow the browser toolbox to enable/disable multiprocess behavior on-demand (bug). The user can switch between two modes. The devtools console is now significantly faster! If you are a developer who heavily uses the console, this should be a substantial quality of life improvement. Firefox 100 goes out today! A milestone release, but also business as usual! Congratulations to contributors who helped get Firefox 100 out the door!

GNU IceCat
GNU IceCat

GNUzilla is the GNU version of the Mozilla suite, and GNU IceCat is the GNU version of the Firefox browser. Its main advantage is an ethical one, it is entirely free software. While the Firefox source code from the Mozilla project is free software, they distribute and recommend nonfree software as plug-ins and addons. Also their trademark license imposes requirements for the distribution of modified versions that make it inconvenient to exercise freedom 3. Extension that encrypts your communications with many major websites, making your browsing more secure. Blocks privacy trackers while in normal browsing mode, and all third party requests when in private browsing mode, based on Adblock Plus. Adds a custom “about:icecat” homepage with links to information about the free software and privacy features in IceCat, and checkboxes to enable and disable the ones more prone to break websites.

Firefox Developer Edition
Welcome to your new favorite browser. Get the latest features, fast performance, and the development tools you need to build for the open web. All the latest developer tools in beta, plus experimental features like the multi-line console editor and WebSocket inspector. A separate profile and path so you can easily run it alongside release or beta Firefox. Preferences tailored for web developers, browser and remote debugging are enabled by default, as are the dark theme and developer toolbar button. Firefox DevTools now grays out CSS declarations that don’t have an effect on the page. When you hover over the info icon, you’ll see a useful message about why the CSS is not being applied, including a hint about how to fix the problem. The new Firefox DevTools are powerful, flexible, and best of all, hackable. This includes a best-in-class JavaScript debugger, which can target multiple browsers and is built in React and Redux.

The SeaMonkey project is a community effort to develop the SeaMonkey Internet Application Suite (see below). Such a software suite was previously made popular by Netscape and Mozilla, and the SeaMonkey project continues to develop and deliver high-quality updates to this concept. Containing an Internet browser, email & newsgroup client with an included web feed reader, HTML editor, IRC chat and web development tools, SeaMonkey is sure to appeal to advanced users, web developers and corporate users.

The Internet browser at the core of the SeaMonkey Internet Application Suite uses the same rendering engine and application platform as Mozilla Firefox, with popular features like tabbed browsing, feed detection, popup blocking, smart location bar, find as you type and a lot of other functionality.

    "Good browser"

    Posted 2025-06-19

    Pros: Sneak peeks on the stable/normal release of Firefox. Better developer tools. Customization and speed.

    Cons: Google being the default search engine which is a privacy risk. Slight data collection being on by default.

    Overall: Firefox Nightly is an amazing browser for developers and the average user who wants to test new updates and get them earlier.
