Clicking "Presenter view" on a Google Slides deck in Orion does nothing. The action works correctly in Safari, Chrome, and Firefox. Enabling Orion's compatibility mode does not resolve the issue.
Steps to reproduce
- Open any Google Slides presentation in Orion (e.g.
https://docs.google.com/presentation/...).
- Click the dropdown arrow next to the "Slideshow" button in the top-right.
- Select "Presenter view."
Expected behavior
A new window opens showing the slides, with a separate presenter window containing speaker notes and slide previews (matches Chrome/Firefox behavior).
Actual behavior
The presentation loads for a second and then crashes. Google then provides debugging text.
Console output (root cause)
Blocked script execution in 'about:blank' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.

Global Code (m=app:12634)
Google's presenter view code opens a new window (initially about:blank) and injects a script to render the notes UI. WebKit blocks the injected script because the frame inherits sandbox flags without the allow-scripts token. Chromium permits this operation, which is why the feature works in Chrome and Firefox but not Orion.
Environment
- Orion version: Version 1.0.6 (145), WebKit 624.1.7
- macOS version: 26.4.1 (25E253)
- Compatibility mode: enabled (issue also reproduces with it disabled)
- Content blockers: enabled (issue also reproduces with it disabled)
Additional notes
- The stack trace and error are identical with compatibility mode on vs. off, suggesting this is not a user-agent sniffing issue.
- Disabling content blockers for
docs.google.com does not resolve the issue.
- Happy to provide a test deck or additional console/network logs if helpful.
- Presenter Mode works find in Safari, Chrome, Brave
When I select "Presenter view" from the Slideshow dropdown, Orion should open a new window containing the full-screen slide presentation, along with a separate presenter window that displays my speaker notes, a slide preview, a timer, and next/previous slide controls. This is the standard Google Slides presenter experience and matches how the feature behaves in Safari, Chrome, Brave, and Firefox on the same machine.
