STR: 1) Open a fresh nightly 51 browser instance in e10s mode 2) Open https://jakearchibald.github.io/service-worker-benchmark/ 3) Make sure it says "No service worker"... click unregister, close tab, and open new tab if necessary 4) Open network monitor 5) Click refresh 6) Observe that all content tabs are hung (you get the spinny icon) On my beefy win10 desktop this takes probably close to a minute to come back. AFAICT this does not reproduce on dev edition 50 or release 48.
I can not reproduce this on Mozilla/5.0 (Windows NT 10.0; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0
I can't reproduce the problem on my machine. Ben, did you try to switch on/off e10s? Tools -> Options -> General -> Enable multi-process Nightly Honza

I still see some minor jank, but not like my original report. I was probably running into other stuff using the main thread as well. This kind of sucks, but is not as bad as I originally saw.
