What's new in 4.3
Customizable panels and AI assistance that runs on your device.
- New top bar. Tabs scroll on their own strip; menu, minimize and close stay fixed on the right (on phones the ✕ never scrolls away).
- "Panels" menu (like Chrome's "More tools"): open any panel, show or hide panels, reorder them with arrows or by dragging, restore defaults. Your layout is remembered. Ctrl+[ / Ctrl+] switch panels.
- Resizable Styles pane in Elements: drag the divider, double-tap for small/medium/large, or use the arrow keys.
- AI assistance: tap the bubble next to any console error or warning for a clear explanation and a fix. The quick explanation works offline and sends nothing.
- Optional on-device AI (off by default, desktop): a small code model runs inside Firefox's own machine-learning engine. No account, no API key, no server: your code and errors never leave the browser.
- Assistant tips now appear in a thin bar at the top of the panel instead of a floating bubble.
- Tests on real Firefox, desktop and phone: 4.3 suite 48/48, resizable pane 22/22, 4.2.1 privacy 23/23, 4.2 suite 74/74, AI panel 4/4. addons-linter 0/0/0.
