ChromeOS Secure Browser Update

Email Update, July 21, 2025

Dear LEA CAASPP Coordinator or LEA ELPAC Coordinator:

LEAs must install the new ChromeOS secure browser prior to updating to ChromeOS 139, which will become available on August 19, 2025. The new ChromeOS secure browser is now available. Refer to the Secure Browsers web page for additional information on supported operating systems and devices.

Once an LEA updates Chromebooks to ChromeOS version 139, the LEA must install the new ChromeOS secure browser application. The previous ChromeOS version of the secure browser will no longer function.

Please note that the process for installing the application has changed. For detailed instructions on how to install the new ChromeOS secure browser, visit the ChromeOS Basic Secure Browser Installation section of the Technology Guide web page.

LEAs that are currently using the previous version of the ChromeOS secure browser will be able to continue testing using ChromeOS version 138.

For further support, visit the Contact Us web page.

Sincerely,

California Outreach Team
