Install the Browser Control extension

Meetings with browser control use this extension in Google Chrome. It is needed only on the computer that will share a Chrome tab.

Press Check Extension after you finish the steps below.

Looking for the extension on this computer…

Download the extension (ZIP) Download it from the CloudDesk server you use: it contains that server's security key.
Right-click the ZIP and choose Extract All… (Windows) or double-click it (Mac). Keep the extracted folder somewhere permanent, such as Documents\CloudDesk-Extension. Chrome keeps using that folder, so do not delete it.
In Chrome, open chrome://extensions in the address bar.
Turn on Developer mode (top right).
Click Load unpacked and select the extracted folder, the one that contains manifest.json.
Make sure CloudDesk Browser Control is on in the list and shows version 1.8.0 (remove any older CloudDesk card first). Pin it to the toolbar if you want quick access.
Click Details on the card and check that Site access is On all sites (the default). With “On click”, CloudDesk shows Blocked on this site.
Come back to this page. The status turns to Installed · ready by itself within a few seconds. If it does not, press Check Extension.

Nothing happens until someone in your meeting presses Request Chrome Access and you press Accept. The CloudDesk server checks every step; the extension only accepts approvals signed by your CloudDesk server.
After you accept, that person can see and control the tabs of the Chrome window your meeting is in (not CloudDesk itself, Chrome pages, other windows or incognito). Sites you are logged in to in that window are visible to them.
Chrome shows a “CloudDesk started debugging this browser” bar while control is active. That is Chrome’s required notice; it cannot be hidden.
It never controls Windows, File Explorer, other applications or your desktop, and it never records the whole screen.
You can take back control (view only) or revoke at any time: Take back control / Revoke Access in the meeting, or in the extension’s toolbar popup (it shows LIVE while access is on).
Access ends when you revoke it, the time limit is reached, the meeting ends, either person leaves or disconnects, the page reloads, or the browser restarts. It never comes back by itself: a new request and a new Accept are needed.
It reads no passwords, cookies or history and records nothing.

Not installedFollow the steps above. If you installed it while this page was open, reload the page.
Blocked on this siteThe extension is installed but Chrome does not let it run on this address. Open chrome://extensions, click Details on CloudDesk Browser Control and set Site access to On all sites. The page continues by itself.
Wrong addressOpen CloudDesk at http://localhost:3000 (or your https://…devtunnels.ms address). Other addresses need the extension to be rebuilt for them (see README).
Not connectedOpen chrome://extensions, make sure the extension is on, then reload this page.
Update required / update availableDownload the newest ZIP, extract it over the old folder, and press the reload icon for the extension in chrome://extensions.
Download againThe extension came from another CloudDesk server, or this server's security key changed. Download it again from this server, extract it over the old folder and press the reload icon in chrome://extensions.
Chrome says a tab cannot be controlledChrome does not allow extensions on its own pages (such as chrome:// pages or the Chrome Web Store). Use normal websites (http/https) in the shared window.
