Created attachment 8889974 [details] Screen Shot 2017-07-24 at 12.00.05 PM.png I get a consistent tab crash when viewing https://daneden.github.io/animate.css/ with the inspector open. I've attached the screenshot of the console log which refers to this line of code: https://searchfox.org/mozilla-central/source/browser/modules/FullZoomUI.jsm#60 I have the stylo pref turned on, here are some crash ids 5bfd4f54-43aa-454d-a964-882430170724 bp-d21e306b-a7da-4f4b-a128-c46ff0170724 bp-af076808-6840-4abb-ad02-c56ef0170724 With stylo turned on I can reproduce this with a fresh profile. ( bp-a9a3347a-e855-4141-babd-4feb10170725 )
STR 1. open page https://daneden.github.io/animate.css/ 2. open devtools inspector 3. open animations tab in inspector right sidebar
I believe the ZoomUI part is unrelated to the crash, seems like a Stylo content crash.
DevTools is one of the two consumers of compute_distance (the other being SMIL) so it sounds like one of our compute_distance implementations is buggy. And based on bug 1384014 it looks like we're unwrapping something we shouldn't.
