Several browsers do not block third-party cookies by default. However, Safari and Firefox automatically block third-party cookies. Google will soon join Safari and Firefox in blocking third-party cookies in its Chrome web browser.
To avoid a "3rd party cookie" error message, Chrome users may uncheck the option to block third-party cookies manually via the browser's "Settings" page. For step-by-step instructions, please click here.
KAF (Kaltura Application Framework) provides a multi-step user experience, and as such, maintains a user's state over multiple HTTP requests using a session cookie. Without it, the user will lose their session and cannot perform any action within the KAF frame.
As KAF is under a separate domain, cookies are considered 3rd party. We suggest creating a subdomain for KAF to overcome this blocking configuration. Cookies set in iframe pages must be of the same domain as the top page.
If your LMS environment is hosted under your LMS provider's domain, please contact a Kaltura solutions expert before proceeding.
If you have encountered error messages in your LMS integration, please follow the steps below to resolve the issue.
If your LMS Environment is hosted under your domain
Using the Hostnames Module, administrators can set a new alias with their own company or school's domain. By loading KAF through a sub-domain of your LMS environment, the cookie is no longer considered 3rd party, thus browsers will not block them. For example, create a sub-domain for your KAF instance (e.g., if your LMS domain is: lms.univ.edu, create a subdomain of: kaf.lms.univ.edu)
See How to Assign Your Own Domain to a Kaltura MediaSpace or KAF SaaS Instance for more information.
If a "Tab "hostnames" not found!" alert shows, contact your Kaltura representative and ask them to enable the module on your instance.
For technical assistance, please submit a ticket via the Customer Care Portal with the following information:
1. PID and KAF instance.
2. New subdomain for KAF (and a developer key if you are using Canvas)
If you are using Canvas
If you are using Canvas, a developer key must be issued to the new subdomain. An account admin for the school can do this by following this guide: https://community.canvaslms.com/docs/DOC-4675.
A Vanity URL and a Dev Scoped Key are required in both LTI 1.1, and LTI 1.3, to learn more see Kaltura Video App for Canvas Upgrading from LTI 1.1 to LTI 1.3.

If you are using DuckDuckGo
The DuckDuckGo Chrome extension is not supported and using it could lead to potential playback issues.
Apple devices iOS/iPadOS 18 and macOS Sequoia might experience the error "You must enable 3rd party cookies" when attempting to play a video. This is caused by Apple removing a crucial cookie from the system and browser settings. To solve this, please follow the solution above or upgrade to Apple Releases iOS 18.0.1.
