Comment 9

[Luca Greco [:rpl] [:luca] [:lgreco]]

From a quick look to the failures tracked by this intermittent, this test is only failing intermittently on linux64 asan builds (the linux64 ones are from beta where asan is a build type, on nightly seems to be part of the platform name) and so we may disable it on those builds.

The underlying error is raised from the devtools internals, very likely triggered because the test is opening and closing about:debugging and the about:debugging page may still have some pending "Remote Debugging Server" requests (and the asan build is likely slower enough for this race to be able to trigger this kind of failures more easily than other builds).
