Status: RESOLVED WORKSFORME

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

Description

[Andrei Vaida [:avaida]]

Reproducible on:
 * Aurora 35.0a2 (2014-11-04),
 * Nightly 36.0a1 (2014-11-04),
using Windows 7 64-bit, Ubuntu 14.04 LTS 64-bit and Mac OS X 10.8.5.

STR:
1. Launch Firefox using a clean profile.
2. Enable Timeline from the Developer Tools.
3. Click menu → New Window.
4. Open the Browser Console from the Developer Tools.
5. Access a content-heavy website in the 2nd window - (e.g.) http://themify.me/demo/themes/parallax/ 
6. Start recording operations in Timeline for a few seconds, then stop recording.
7. Close the 2nd window and check the console.

Expected result: there are no errors thrown for these actions.

Moving into the Profiler component. Filter on GUTHRIE'S WAVY CAKES.

Please test again with the new perf tool, and reopen if this is still an issue. Thanks!
