Fireside is a stylesheet for Firefox that provides you with a clean UI. Less clutter, more vertical space.

• Vertical tabs (using Tab Center Reborn or Sidebery)
• Zero UI elements taking vertical space
• Auto-collapsing sidebar preserving horizontal space and removing distraction
• Keyboard and mouse support

• Firefox 121 - 133b3, Linux (Wayland)
