An Arc Essentials alternative for Firefox
Landed on Firefox after Arc? Essentials brings Arc's pinned-site grid to Firefox natively — a toolbar popup of your key sites in color-coded spaces, synced via Firefox Sync. One-time $4.99.
What Arc's Essentials gave you
Arc kept your most-used sites in a persistent grid — its "Essentials" — one click away and grouped by Space. After Arc's development wound down, Firefox users were left without it.
How Essentials brings it to Firefox
Essentials is a real Firefox extension — no Chromium needed. Your sites live in a toolbar popup grid opened with Ctrl/⌘+Shift+E, split into color-coded spaces switched with Ctrl+1 – Ctrl+9.
