Now that we have a theory that it's connected to Adobe Cloud fonts, do you think you might be able to start the Firefox profiler, cause the problem, and then stop the profiler? The reason we're so keen on getting a profile is that it's very likely to help us understand what in the world Firefox is doing while it's hung. From here, since we can't reproduce the problem ourselves, we can only guess, and that's got a poor track record.
