User Agent: Mozilla/5.0 (Windows NT 6.1; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20130910160258

Steps to reproduce:

I clicked the new-profile button in Fx 25, it adds one to the list but does nothing else. (I did the Firefox beta update today.)


Actual results:

It gave the following errors in Browser Console:

[17:09:45.164] [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIProfiler.StartProfiler]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: resource://gre/modules/devtools/dbg-server.jsm -> resource://gre/modules/devtools/server/actors/profiler.js :: ProfilerActor.prototype.onStartProfiler :: line 86"  data: no]
undefined @ resource://gre/modules/devtools/dbg-server.jsm -> resource://gre/modules/devtools/server/main.js:829

[17:09:45.165] Server did not specify an actor, dropping packet: {"error":"unknownError","message":"error occurred while processing 'startProfiler': [Exception... \"Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIProfiler.StartProfiler]\"  nsresult: \"0x80040111 (NS_ERROR_NOT_AVAILABLE)\"  location: \"JS frame :: resource://gre/modules/devtools/dbg-server.jsm -> resource://gre/modules/devtools/server/actors/profiler.js :: ProfilerActor.prototype.onStartProfiler :: line 86\"  data: no]\nundefined"} @ resource://gre/modules/devtools/dbg-client.jsm:641


Expected results:

Profiler should start a new performance profile.
I just got this again in Firefox 26. Even closing and reopening the debugger didn't fix it.

15:35:09.742 error occurred while processing 'startProfiler: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIProfiler.StartProfiler]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: resource://gre/modules/devtools/dbg-server.jsm -> resource://gre/modules/devtools/server/main.js -> resource://gre/modules/devtools/server/actors/profiler.js :: <TOP_LEVEL> :: line 86"  data: no] main.js:923

Profiler is a no-show in FF29
Component: Untriaged → Developer Tools: Profiler
Version: 24 Branch → Trunk
Whacky...

Using FF29, I cannot get the profiler to work.  Yet, using FF29 devtools to connect to Android for remote debugging, the profiler works (slowly, yes, but it works).

Go figure...
Can you post the contents of your about:support page? Also, what does the following line print if you paste it in the Browser Console (Ctrl-Shift-J)?

startProfiler ... note that I've included the complaints from the previous attempt to start prof from the tools UI.

This is your problem, profiling is disabled in private browsing mode due to the potential for information leak:

http://dxr.mozilla.org/mozilla-central/source/tools/profiler/nsProfiler.cpp?from=StartProfiler#77

If you need to profile, you will have to use a normal browser window. Granted, the profiler UI for discovering this currently sucks, but bug 896222 will hopefully improve it.

Ha! Good catch. A few releases back, I'd been testing the new tabs UI stuff and left it that way... Thanks.
