Special features

  • Firefox Sync is supported, and can share tabs across devices. It is cross-compatible with most other Firefox derivatives.
  • Support for progressive web apps is included.

    UI and customization

Floorp builds on Firefox by adding features including vertical tabs, multi-functional sidebars, and support for custom CSS. It also includes the ability to transfer toolbars to the title bar and to hide the sidebar until the mouse hovers over it. In addition, it supports very detailed customizations, including switching or hiding the bookmark label, moving toolbars to unconventional locations, and having the tab bar and URL bar on the same line. The default theme is "Lepton" but it can be changed to other themes, including previous default "Photon" and operating system-specific themes.
Floorp also includes a mode called "split view", which allows users to view multiple tabs at once without opening a separate window.

Privacy

Floorp includes several privacy features, including fingerprinting protection, and the ability to disable features such as WebGL and WebRTC. It also disables telemetry from Mozilla, while still including Firefox's anti-tracking features.
Floorp also includes "share mode", which allows users to share their screens while hiding the bookmark bar and sidebar.
