As of 2 days ago, I was accessing recorded lectures via my school's online resource which stores vids in Kaltura.

Quite literally I was watching vids at noon, went to lunch and came back to resume an hour or two later, and suddenly I'm getting this message: " It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application. To resolve this issue, please update your settings to allow 3rd party cookies."

This is only coming up on my Surface tablet, which is the main hardware I use in class, and not on my Dell laptop which, I only use at home and for tests.

I've read through the thread from Jan 2022 and performed all the work arounds with no satisfaction.

I'm frantic. I don't want to use the other browsers, but I may have to for the next 2 years if I can't find a fix.

Can ANYBODY please help? ASAP?

1. Check Firefox Cookie Settings

Open Firefox. Click on the three horizontal lines (menu) in the upper right corner. 

Select Options (or Preferences on macOS).

Go to the Privacy & Security panel. Under the Cookies and Site Data section, ensure that "Standard" is selected. If you want to allow third-party cookies, you can also select "Custom" and make sure that "Cookies" is set to "Cross-site and social media trackers."

2. Allow Cookies for Kaltura

In the same Cookies and Site Data section, click on Manage Exceptions. 

Add the Kaltura URL (e.g., *.kaltura.com) and set it to Allow.

3. Clear Cache and Cookies 

Go to the Privacy & Security panel again.
Under Cookies and Site Data, click on Clear Data.

Check both options (Cookies and Site Data, Cached Web Content) and click Clear.

4. Disable Enhanced Tracking Protection 

Click on the shield icon in the address bar when you're on the Kaltura site.

Toggle the Enhanced Tracking Protection to Off for that site.

5. Check for Extensions

Sometimes, browser extensions can block cookies. Disable any ad blockers or privacy extensions temporarily to see if that resolves the issue. 6. Update Firefox

Make sure you are using the latest version of Firefox:

Click on the menu button and select Help. Click on About Firefox. Firefox will check for updates and download them automatically.

7. Restart Firefox

After making these changes, restart Firefox and try accessing the Kaltura site again. 8. Test in Safe Mode

You can also try running Firefox in Safe Mode to see if the issue persists:

Click on the menu button, go to Help, and select Restart with Add-ons Disabled.
