1157833 - All content tabs crash when recording a profile [e10s]

Status: RESOLVED WORKSFORME

(DevTools :: Performance Tools (Profiler/Timeline), defect)

Description

[Jeff Griffiths (:canuckistani) (:⚡︎)]

Attachment: log of a session using the profiler

Using current nightly

STR:

1. open any page, eg amazon.com
2. start recording a profile
3. hit reload on the tab, use case is to record a profile of the page loading

Expected: complete recording

Actual: all tabs crash! The profiler sees to stop recording after clicking stop 3 times exactly, but the realtime timeline continues to be animated.

Jeff, I don't understand what "recording a profile" is. Can you expand on that to make step 2 clearer. thanks

In nightly's performance tool in devtools, clicking the "start recording" button starts "recording a profile". For what it's worth, I haven't seen this in a bit, and also suspect it was due to enabling memory recording (devtools.performance.ui.enable-memory iirc)
