Case for Firefox

If you browse the web, you're using a browser. But are you using it efficiently?

Most users barely scratch the surface of their browser's capabilities. They reach for the mouse for every action, click through menus for basic tasks, and never realize that their browser could be controlled almost entirely from the keyboard—or even from the command line.

Firefox stands out as a browser that respects your efficiency. Unlike proprietary alternatives, Firefox offers:

• True keyboard-first navigation: Almost every action has a keyboard shortcut
• Command-line interface: Launch, configure, and control Firefox from the terminal
• Open-source transparency: Know exactly what your browser does
• Privacy by design: No telemetry tracking by default
• Customization freedom: Modify everything from shortcuts to UI

Why keyboard shortcuts matter

Moving your hand from keyboard to mouse and back wastes time. Studies show that proficient keyboard users can complete tasks 20-40% faster than mouse-dependent users. More importantly, keyboard shortcuts maintain your flow state—that precious mental state where work feels effortless.

Why CLI matters

Command-line control enables:

• Automation: Script repetitive browser tasks
• Remote management: Control Firefox on headless systems
• Profile management: Quickly switch between work/personal profiles
• Development workflows: Integrate Firefox into your build process
• Troubleshooting: Launch with specific flags for debugging
