Thanks for the heads up - I'm on it.

I believe that with Bug 178846 landed the frequency of this intermittent is back where it was prior to Bug 1748005:

It seems most of the leaks happen for dom/websocket/tests/test_websocket_mixed_content.html

Flags: needinfo?(valentin.gosu)

I added, dom/websocket/tests/test_websocket_mixed_content.html, let me see what I can find.

Flags: needinfo?(acreskey)

Just pushed Bug 1802227 which includes fixes to these leaks. Will monitor from here.

Flags: needinfo?(acreskey)

No occurrences of any leaks since the patch in Bug 1802227 landed (so far).
So this seems promising.
If this continues, I can apply the technique to other tests in the webSocket suite and follow up to find out why clearing the .src attribute is needed.

This looks to be greatly reduced, with the 7 of 8 leaks reported in branches that don't have the fix. But not entirely fixed as there is one on autoland last week.
