Component: Untriaged → Developer Tools: Profiler
Summary: Profiler frequently stops working → Profiler does not start again. [frequently stops working]
as :Aleksej posted, and tested myself, was able to recreate this on Fx35 Beta (OSX), but in Nightly (Fx37), I was unable to reproduce this. Can you confirm that this is no longer an issue on Nightly, Liam?
This reproduces for me in the current release version of Firefox (35) both on Windows and Linux. This does not reproduce on Nightly on Linux (38.0a1 (2015-01-23))
So looks like this is fixed.
