Website access troubleshooting

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.

Firefox

Check extension permissions

Firefox does not use Chrome’s new access menu. Follow these steps only if Firefox reports that KoalaSync lacks website access.

  1. Open Add-ons and themes, then select Extensions.
  2. Open KoalaSync and select Permissions or Permissions and data.
  3. Allow the requested website access.
  4. Return to the video site, reload it, and select the tab again.

Why this suddenly happened

Your browser started withholding website access

Chrome is gradually rolling out new per-site controls for extensions. The rollout can reach individual browsers or profiles without a KoalaSync update, so KoalaSync may appear to stop working from one day to the next while another browser still works normally.

The room connection can remain online, but the browser blocks KoalaSync from reaching the video player. Granting KoalaSync access to the affected video website and reloading that tab restores playback synchronization.
