15:48:38: Starting simulator...
15:48:38: Simulator ready. Connecting.
15:48:38: connecting to localhost:44739
15:48:58: connection timeout. Possible causes: didn't click on 'accept' (prompt).

Environment Informations:

- Mozilla/5.0 (X11; Linux x86_64; rv:32.0) Gecko/20100101 Firefox/32.0
- ADB Helper installed
This looks as a regression. Using nightly buildings I track 2014-05-15 as a good version and 2014-05-17 as a bad one.
This sounds like a dupe of bug 1012869.  I'll be attaching a fix there soon.  Once it's in Nightly, it would be great if you could test this again, as it's hard for me to reproduce this problem locally.
Stinnett,

Thanks for the help and sorry for the bug be a little hard to reproduce. I apply your patch, build Firefox but it didn't solve the problem. Let me know if a dump of my system will help and how can I provide it.

Thanks for testing this locally, that's quite helpful!  Since you and Paul (in bug 1012869) both say the patch doesn't help, that strengthens my belief that it's the same root problem (even though Paul says it does not happen for him on Linux).

Can you test with other simulator versions as well, to see if they have the same issue?  For example, try the 1.3 simulator.  This will help confirm that it's a purely client-side problem.

Also, if you try connecting to the simulator again, does it eventually work?  Or does it fail every time for you?
Same problem with Simulator 1.3:

14:13:31: connecting to localhost:6000
14:13:32: disconnecting
14:13:32: disconnected
14:13:35: Found simulator: Firefox OS 1.3
14:13:35: Starting simulator...
14:13:35: Simulator ready. Connecting.
14:13:35: connecting to localhost:55994
14:13:55: connection timeout. Possible causes: didn't click on 'accept' (prompt).
14:13:55: disconnecting
14:13:55: disconnected

I'm using Arch so it can be happen due some bleeding edge library "only" available at Arch.

I couldn't try reconnect to the simulator because there was such option for Firefox 55cb60250013 (your patch) and c8288d0c7a15 (nightly) using Simulator 1.3 and 2.0.

When I said "reconnect", I was assuming that the bottom bar of the App Manager says "Connecting... [Cancel]" while it tries to connect.  If you cancel and start the simulator again, that's what I mean by "reconnect".

It's possible it a library issue, but since you found a regression range where many changes were made to the transport that sends DevTools packets, I don't think that would be it.  But for completeness, you can enable verbose logging[1] for the simulator, as that could give us more data to go on.  You'll need to set the pref it describes, and then open the Browser Console to see logging messages.

Same problem with "cancel and start the simulator again".

I didn't have time to use bisect and build Firefox for each commit of bisect (since this will take many hours).

I couldn't enable verbose logging because [1] is out of date. Search for extensions.fxos_1_3_simulator at Firefox 29.0.1 or high give no option.

Okay, good to know.

That's fine, I am almost positive it's from bug 797639, which is inside your range.

The prefs do not exist by default for any version of Firefox.  Instead you need to add a new pref with the given name (you can create it by right-clicking in the about:config UI).  The ones listed are just examples.  For example, to affect the 2.0 simulator, the pref name would be "extensions.fxos_2_0_simulator@mozilla.org.sdk.console.logLevel".
I've added a new patch to bug 1012869 that replaces the previous one.  If you could try that on your system, it would be quite helpful!

Stinnett, thanks very much for the patch. Looks like that it solves the problem.

Thanks for your help in testing the fix!  I'll mark this as a dupe.
