Issues with Blackboard and Zoom with Enhanced Protection

more options

I am an administrator at a university and we use Blackboard and Zoom as a couple of the tools at our university. We install Firefox on all of our PCs across campus. After a recent update, when our instructors try to launch Zoom using the integration setup in Blackboard, the meeting fails to launch. We have found that disabling Enhanced Protection fixes this issue. Is there a way to add this exception to an install file that can be sent across many PCs on our campus? We have hundreds of PCs and going from one to another to install this exception would not be practical.

Do you have any suggestions? Justin

Hi Justin, most likely this is caused by the rollout of "Total Cookie Protection" which partitions third party cookies. Individual site exceptions should resolve the issue but it often is difficult to identify exactly which servers need to be able to set "global" third party cookies and which need to read them. See: Total Cookie Protection and website breakage FAQ.

Rolling Back Total Cookie Protection

From the end-user perspective, this is set on the Privacy & Security panel of the Settings page, selecting Custom tracking protection and adjusting the level of cookie blocking:

Behind the scenes, that modifies the default cookie blocking level set in this preference:

network.cookie.cookieBehavior

from 5 (Total Cookie Protection partitions cross-site cookies) to 4 (block known trackers only).

From the Group Policy perspective -- https://github.com/mozilla/policy-templates#cookies -- it looks like you would set that using:

Software\Policies\Mozilla\Firefox\Cookies\Behavior = "reject-tracker"
