Introduce the shared surfaces frontend service and stylesheet so Browser and Desktop can register docked or floating live UI without special cases in modals.js. Update Browser and right-canvas integration to preserve active viewers across canvas/modal switches and avoid creating blank tabs unless explicitly requested.
Extend Browser into a reusable panel that can run in either the Universal Canvas or the floating modal. Add canvas registration, dock/undock behavior, and keep the existing modal path working as a fallback.
Stabilize tab switching with viewer tokens and stale-frame rejection, prevent command snapshots from crossing active tabs, and keep tab changes responsive.
Improve canvas navigation and scrolling by making screencast polling non-blocking and removing page-settle waits from wheel input, so the visible frame updates promptly without stretch/catch-up artifacts.
Polish Browser busy feedback with a spinner-only status affordance to avoid misleading “updating browser” copy.
Replace the Browser viewer’s screenshot polling with CDP screencast streaming for much smoother navigation. The runtime now starts/stops CDP screencasts cleanly, acknowledges frames, drops stale frames, and keeps the WebSocket payload compatible with the existing viewer.
Also fixes modal viewport sizing by sending the initial stage dimensions on subscribe, applying CDP emulation sizing before the first frame, avoiding image stretching, and increasing screencast JPEG quality to 92. Regression coverage was added for the screencast path, frame ack/drop behavior, viewport sizing, and UI rendering assumptions.
-- Still needs thorough performance audit and optimization --
Refine the Browser modal UI with more native-feeling tabs, consistent chrome controls, right-side tab close buttons, and a cleaner extension dropdown. Move the Browser LLM preset into the dropdown with the active Main Model summary, simplify extension settings, remove the global extension enable switch and legacy extension root behavior, and add per-extension enable toggles.
Also updates the Chrome extension install/review flow with contextual warning copy, “Scan with A0”, cleaner labels, hidden empty extension state, and regression coverage for the new Browser UX.
- Always launch Browser with full Playwright Chromium instead of switching between headless shell and extension mode
- Cache Chromium under /a0/usr/plugins/_browser/playwright with legacy lookup for existing installs
- Store installed Browser extensions under /a0/usr/plugins/_browser/extensions with legacy extension-root compatibility
- Show clearer first-run Chromium install messaging and extend the initial Browser timeout
- Fix Browser spinner animation for startup and extension install states
- Update Docker Playwright install script and regression coverage
Introduce the new built-in Browser plugin for Agent Zero, replacing the legacy
browser-use-based browser agent with a direct Playwright-powered browser tool,
live WebUI viewer, browser session controls, status APIs, configuration, and
extension-management support.
Add browser-specific modal behavior so the browser can run as a floating,
resizable, no-backdrop window, including modal focus, toggle, and idempotent
open helpers for richer WebUI surfaces.
Remove the old `_browser_agent` core plugin and the `browser-use` dependency,
then clean up stale browser-model wiring and references across agent code,
model configuration docs, setup guides, troubleshooting docs, skills, and
Agent Zero knowledge.
Update regression and WebUI extension-surface coverage for the new browser
architecture and modal behavior.
The legacy browser-use implementation has been extracted from core so it can
continue separately as a community plugin published through the A0 Plugin Index for any user or professional that were relying on it for workflow.
