Marble Browser is a Desktop web browser and supports the Linux, macOS, Windows operating systems. It's a relatively new browser; in development for about one year.

A Firefox fork that aims to restore the Photon user interface, along with native controls that were removed in newer versions of Firefox.

The release date and the latest version number of Marble Browser is displayed on the download page - this is very useful - it means you can easily tell how recently the latest version has been released. Using versions of software that were released a long time ago is bad security practice; the software may have old, unpatched bugs in it.
