Description

[Marco Castelluccio [:marco]]

I'm trying to use the profiler with a Flame (Firefox OS 2.0). I can start the profile, but I can't stop it. This is the error I'm seeing in the browser console:

The new profiler (performance) tool, which will be made available in Fx39, should fix this from bug 1130200

This should be resolved in latest nightly profiler, with B2G 2.0-2.2. Please reopen if this is not the case. Thanks!
