Bug 1630268 showed that we very likely have memory leaks when we open and close devtools, which is a problem for the test harness that runs many tests consecutively. Alexandre provided a detailed approach to investigate in https://bugzilla.mozilla.org/show_bug.cgi?id=1630268#c25.

http://techno-barje.fr/talks/2020-06-mochitest-memory/
Devin also shared to the devtools team a record of this lightning talk.
