Command Center par jagajaga

Command Center is a fast, keyboard-driven launcher for Firefox.

Press Cmd+Shift+Space (Ctrl+Shift+Space on Windows/Linux) anywhere to open a centered, Spotlight/Alfred-style search box, then start typing:

• Fuzzy-search your open tabs first, then your browsing history.
• Enter switches to the matching tab, or opens a history result in a new tab.
• Cmd+Enter ignores the list and acts on what you typed — open it as a URL if it looks like one, otherwise run a Google search.
• Cmd+Backspace (or the × button) closes the highlighted tab without leaving the palette.
• Arrow keys (or Ctrl+N / Ctrl+P) to move, Esc to close.

Customisable: open the add-on's Settings to rebind the shortcut to any combo, remap the in-palette keys (open, Google/URL and close-tab), and set how many results are shown.

The overlay is style-isolated in a Shadow DOM and captures keystrokes so the underlying page's shortcuts don't interfere. Site icons are shown next to results. No accounts, no analytics.
