I am on OS X 10.10.5 and have a USB connected Flame-KK device that shows up using adb devices I open the WebIDE in Nightly 43.0a1 (2015-09-21) and the device is not listed. I subsequently close Nightly 43.0a1 (2015-09-21) and start an old version of Firefox 37.0.2 and attempt the same, to connect to the device using WebIDE. This works. Using Nightly 43.0a1 (2015-09-21) and attempting to connect to the device using WebIDE the browser console contains the stack trace.... Module `./adb-socket` is not found at resource://adbhelperatmozilla.org/adb-socket.js: @resource://adbhelperatmozilla.org/adb-client.js:13:23 @resource://adbhelperatmozilla.org/adb-running-checker.js:16:16 adb_start@resource://adbhelperatmozilla.org/adb.js:104:5 onADBStart@resource://adbhelperatmozilla.org/main.js:41:3 EventEmitter_emit@resource://gre/modules/devtools/event-emitter.js:147:11 enable@resource:///modules/devtools/webide/runtimes.js:304:5 _enableScanner@resource:///modules/devtools/webide/runtimes.js:169:5 enable@resource:///modules/devtools/webide/runtimes.js:164:7 exports.AppManager.init@resource:///modules/devtools/webide/app-manager.js:60:5 ProjectList@resource:///modules/devtools/webide/project-list.js:36:3 @chrome://webide/content/project-listing.js:11:19

I've heard that main culprit is TCPSocket changes to WebIDL (bug 885982).

:gerard-majax already debugged this exception and the SDK loader is hidding the real exception here :/ This error is related to bug 885982. https://github.com/mozilla/adbhelper/blob/master/adb-socket.js#L21-L25 let scope = Cu.Sandbox(Services.scriptSecurityManager.getSystemPrincipal()); scope.DOMError = Cu.import('resource://gre/modules/Services.jsm').DOMError; Services.scriptloader.loadSubScript("resource://gre/components/TCPSocket.js", scope); scope.TCPSocket.prototype.initWindowless = function () true; return new scope.TCPSocket(); We were fetching a TCPSocket instance from a Sandbox, but it looks like, now, with the WebIDL, we have to set the related pref AND have a document instance. That is quite unfortunate, especially the pref. http://mxr.mozilla.org/mozilla-central/source/dom/webidl/Navigator.webidl#439 Josh, Do you think we can easily fetch a TCPSocket instance from chrome code (without setting the pref)?

Not as the code exists today. It may be possible to change the WebIDL files to use `Func=ShouldTCPSocketExist` instead of `Pref=` and `CheckAll=`, where ShouldTCPSocketExist would check the following: - is the global using a system principal (something like http://mxr.mozilla.org/mozilla-central/source/dom/base/URL.cpp#161 and calling nsContentUtils::IsSystemPrincipal) - is the preference enabled - does CheckAnyPermissions return true (https://dxr.mozilla.org/mozilla-central/source/dom/bindings/BindingUtils.cpp?from=checkanypermissions#2427) Andrew, you made a comment about socket.jsm in https://bugzilla.mozilla.org/show_bug.cgi?id=885982#c54 but I don't see that file anywhere.

(In reply to Alexandre Poirot [:ochameau] from comment #2) > That is quite unfortunate, especially the pref. Note that bug 1079648 covers flipping the pref on Firefox and includes some minimal discussion of removing the preference in general.

Here is a patch to use WebIDL's TCPSocket. It requires a firefox build with bug 1207090's patch applied. It also cleans up adb.js from duplicated code with adb-client.js. (I made two distinct commits to help the review)

I'm now waiting for bug 1207090's review before proceeding.

Comment on attachment 8664769 [details] Pull request 18 I just pushed a new revision, with a bug fixed on release (was returning new TCPSocket() result instead of socket.open() in release-TCPSocket.jsm codepath!) Platform patch re-landed, hopefully it will stick this time. Asking review early in order to help releasing the addon ASAP.

Comment on attachment 8664769 [details] Pull request 18 Looks good to me! I'll test and release once the `TCPSocket` change lands in Firefox.

Merged: https://github.com/mozilla/adbhelper/commit/558d60630ec1d1ad0d7dab883b6fa74d611d7728 Preparing a new add-on release now.

ADB Helper 0.8.1 submitted to AMO, waiting on approval.

ADB Helper 0.8.1 has been released. It may take a few hours for the update to be available due to CDN caching.

As a side note, only 44 will work for the moment. 43 still needs bug 1207090 to be uplifted.
