Swiftfox was a web browser based on Mozilla Firefox. It was available for Linux platforms and distributed by Jason Halme. Swiftfox was a set of builds of Firefox optimized for different Intel and AMD microprocessors. Swiftfox was freely downloadable with open source code and proprietary binaries. Firefox extensions and plugins were compatible with Swiftfox, with notable exceptions. The name Swiftfox comes from the animal swift fox. Swiftfox differs from Firefox by a limited number of changes, and builds for different processors. Swiftfox was discontinued at some point prior to April 2017, and the project homepage now redirects to the creator's private Twitter account.
Pango is not included in the build. This means that Unicode fonts remain supported, but without certain extra features provided by Pango. This simplification reduces the binary size, and reduces rendering.

License
The same as Firefox, the Swiftfox source code is open-source, with the source code under MPL 1.1 except for parts relating to branding. Unlike Firefox, the Swiftfox binaries have a proprietary license which does not allow redistribution. According to the author, this is to prevent the possibility of any confusion with tainted versions. The name Swiftfox is trademarked by Jason Halme, and accordingly cannot be used on other third party Firefox builds without his permission.
Debian
Swiftfox binaries are available as Debian packages from . The proprietary binary license prevents Debian and other Linux distributions from having Swiftfox available as part of a distribution, so to redistribute Swiftfox one would have to change the name and icons.
