In Bug 1524276, we'll group the anti-tracking warnings messages.
Even if we don't have the full details of it at the moment, we are probably going to group them from the 1 message location.

Let's take an example.

Here's a view of the console when the first warning message comes in

--------------------------------------------
10:00:00 Request to access cookie or storage
on https://cdn.livefyre.com/livefyre.min.js 
was blocked because it came from a tracker 
and content blocking is enabled.
--------------------------------------------

then let's say we have 10, unrelated logs coming in.

--------------------------------------------
10:00:00 Request to access cookie or storage 
on https://cdn.livefyre.com/livefyre.min.js
was blocked because it came from a tracker 
and content blocking is enabled.
--------------------------------------------
10:00:01 log #1
--------------------------------------------
10:00:02 log #2
--------------------------------------------
10:00:03 log #3
--------------------------------------------
10:00:04 log #4
--------------------------------------------
10:00:05 log #5
--------------------------------------------
10:00:06 log #6
--------------------------------------------
10:00:07 log #7
--------------------------------------------
10:00:08 log #8
--------------------------------------------
10:00:09 log #9
--------------------------------------------
10:00:10 log #10
--------------------------------------------

Okay. So now let's say a new anti-tracking message is added. We create a group and put our 2 messages in.

--------------------------------------------
10:00:00 ▶︎ Request to access cookie or 
storage was blocked ❷
--------------------------------------------
10:00:01 log #1
--------------------------------------------
10:00:02 log #2
--------------------------------------------
10:00:03 log #3
--------------------------------------------
10:00:04 log #4
--------------------------------------------
10:00:05 log #5
--------------------------------------------
10:00:06 log #6
--------------------------------------------
10:00:07 log #7
--------------------------------------------
10:00:08 log #8
--------------------------------------------
10:00:09 log #9
--------------------------------------------
10:00:10 log #10
--------------------------------------------

In the case the 10 log messages were tall enough to push the first warning messages out of the viewport, the user might miss that a new warning messages came in, which could be an issue.

We discussed a few options with Harald to still notify the user, without being to noisy (see attachment).
