Browser Permissions:

Mozilla Firefox

If you haven't completely blocked screen sharing on Firefox you will see a pop-up asking if you want to allow Brainstork to access your screen. You can check this article to see how you can share your screen on various browsers.

1. Click on the "Permission" field just to the left of the website address.
2. Find "Share the Screen" in the list and click the "x" next to it.

3. Now you can retry the screen share, click the "Share" button on the toolbar.
4. Click the "Share Screen".

Google Chrome

Currently, Chrome doesn't have any custom settings for screen access, so if you're having trouble or getting an error, go to the Operating System Permissions area for further troubleshooting or use the system check to figure out what is wrong.
