A Chrome extension that injects a Windows-style taskbar overlay (with a live clock) onto every page. Intended for use with Kernel cloud browsers driven by the Computer Use API, so screenshots look like a real desktop.
Upload the unpacked extension to your Kernel org:
kernel extensions upload ./windows-taskbar --name windows-taskbarThen attach it when creating a browser:
kernel browsers create --extension-name windows-taskbarThe taskbar defaults to the browser's system time zone. To override, either:
1. Use the extension popup
Click the toolbar icon (or open chrome://extensions → "Extension options") and set a time zone like America/New_York. The setting is stored in chrome.storage.local.
2. Set it programmatically over CDP
Useful when the extension is attached on browser create and you want a specific zone without UI interaction. From any page running the content script:
await page.evaluate(() => new Promise((r) =>
chrome.storage.local.set({ timeZone: "America/Los_Angeles", hour12: true }, r)
));Valid timeZone values are any IANA name supported by Intl.DateTimeFormat. Pass null to fall back to the system zone.
The extension is plain HTML/CSS/JS — no build step.
