  • uMatrix is the only extension
  • uMatrix with default lists/settings

Supporting evidence

The problem is reportet in the deprecated issue tracker and there was no update since Feb. 2018. Firefox changed the API since version 59 according bugzilla. Is this issue still in progress or do I have to disable First Party Isolation?

Can you still reproduce it with the Steps given in that old issue ?

I still get the error message in the logger that the delete of the cookie failed. Attached a screenshot:

So the issue still exists

Is this issue still being worked on? The issue is still present in ESR68.1 I am using.

There are error messages in the Browser Console:
Unchecked lastError value: Error: First-Party Isolation is enabled, but the required 'firstPartyDomain' attribute was not set. for the calls to chrome.cookies.getAll and chrome.cookies.remove in vAPI.cookies.getAll and vAPI.cookies.remove respectively.

Maybe adding firstPartyDomain attribute would finally resolve this issue?
