Mozilla Firefox is a fast, full-featured web browser that's easy to use. It has lots of great features including popup-blocking, tabbed-browsing, integrated search, improved privacy features, automatic updating and more. Plus, thanks to the PortableApps.com launcher bundled in Mozilla Firefox - Portable Edition, it leaves no personal information behind on the machine you run it on, so you can take your favorite browser along with all your favorite bookmarks and extensions with you wherever you go.

Intelligent Start

Firefox Portable now uses an intelligent start system that keeps track of where you're running it from. That way, if you run it a second time from the same location or move to another PC that happens to give you the same drive letter, it won't have to do as much to start Firefox up.

Alternate INI Locations Dropped

To improve startup time, the alternate directory layouts for the FirefoxPortable.ini file have been dropped. It will need to be placed next to FirefoxPortable.exe. If you use an INI, you'll also need to update it with the new INI options.

Most Alternate Directory Layouts Dropped

To simplify the launcher, all alternate directory layouts have been dropped except placing the launcher one directory above the FirefoxPortable directory.

Improved Unicode Support

Firefox Portable has improved support for unicode, so you can drop a file with non-ASCII characters right on FirefoxPortable.exe and open it up.

Improved Live CD Support For Windows 95/98/Me

Live mode has been improved for better compatibility with most Windows 95, 98 and Me systems.
