As these are all beta flag changes not sure how we can find the exact culprit

None of them caused a similar change on autoland?

You can rule out Bug #1703944, Bug #1697074, and Bug #1707099, because those are all for enabling EV for root certificates that are being added in Firefox 90.

There's a very little chance that bug 1713820 caused this. It could only happen if temporary storage was broken so it failed to initialize and we reported a few extra lines in the browser console (only the failure reporting to the browser console is new).

We don't have datapoints anymore from where the alert was triggered, and considering the 2% regression, I'll close this as WONTFIX.
