# Connected, but the video tab does nothing?

Your browser may be withholding KoalaSync’s access to that website. The room connection can still look healthy while KoalaSync cannot read or control the player.

Immediate workaround — no extension update required

## Allow KoalaSync in your browser now

1. Keep the affected video website open.
2. Open the browser’s extensions menu next to the address bar.
3. If KoalaSync appears under Access requested, select KoalaSync to grant access.
4. If that section is missing, open KoalaSync’s menu or extension details and set website access to On this site or On all sites.
5. Reload the video page once, open KoalaSync, and select the video tab again.

This manual workaround works even while KoalaSync 2.6.2 is still waiting for approval or rollout in your browser’s extension store.

This is not a new KoalaSync permission.

Modern browsers let users, profiles, and administrators withhold extension access per website. Chrome’s newer extension menu makes that existing control much more visible. KoalaSync 2.6.2 detects the blocked state and adds a guided recovery action after the store update reaches you; the manual steps above work immediately on older KoalaSync releases.

Chrome, Edge, Brave, Opera, Vivaldi

## Allow KoalaSync on the current site

1. Keep the affected video tab open.
2. Open the browser’s extensions menu near the address bar.
3. Under Access requested, select KoalaSync and allow access.
4. In browsers with the older menu, right-click KoalaSync and choose This can read and change site data, then allow the current site.
5. If needed, open KoalaSync’s extension details and change site access to On this site or On all sites.
6. Reload the video tab and select it again in KoalaSync.

3. Allow the requested website access.
4. Return to the video site, reload it, and select the tab again.

Why access is needed

## KoalaSync must reach the player you selected

KoalaSync injects a local content script into the selected tab so it can find the HTML5 player, read its playback position, and apply play, pause, and seek actions. The video and audio stream never leave your browser. Only synchronization state is sent through the relay.

Access is requested for the website origin shown in the popup. Browser-internal pages such as chrome://, edge://, and about: cannot be controlled. Local files may also require the separate Allow access to file URLs switch in the extension details.

Still not working?

## Run these checks in order

- Update KoalaSync in both browsers. Friends using different releases should update before testing again.
- Reload the video page after granting access. An already-open page may still have the old blocked state.
- Open KoalaSync and reselect the exact tab containing the player.
- Confirm the debug report says Video Found. A page without a standard player may need site-specific support.
- Temporarily test without another extension that also modifies the player.
- If it still fails, collect a debug report from each participant before leaving the room.
