Need Help Locating a JavaScript Code Module

[AlbertG]

Greetings!

Here's the scoop: I'm trying to call "browser.management" in an autoconfig script, and can't identify the correct Code Module to bring into context. "ReferenceError: browser is not defined" at the Browser Console is getting quite tiresome...

The listing of potential candidates (per https://developer.mozilla.org/en-US/doc ... de_modules ) includes:

AddonManager.jsm
AddonRepository.jsm
Assert.jsm
BookmarkHTMLUtils.jsm
ctypes.jsm
CustomizableUI.jsm
DeferredTask.jsm
Dict.jsm
DownloadLastDir.jsm
Downloads.jsm
FileUtils.jsm
Geometry.jsm
HTTP.jsm
JNI.jsm
ISO8601DateUtils.jsm
Log.jsm (formerly log4moz)
NetUtil.jsm
openLocationLastURL.jsm
OSFile.jsm
PerfMeasurement.jsm
PluralForm.jsm
PopupNotifications.jsm
Promise.jsm
PromiseWorker.jsm
Services.jsm
source-editor.jsm
Sqlite.jsm
Task.jsm
Timer.jsm
Webapps.jsm
WebRequest.jsm
XPCOMUtils.jsm

In light of the foregoing, which of these many candidates might allow me to successfully scope "browser" in my script?

And, for the record, is there some place to look which has a complete listing of the contents of these modules (and "@mozilla.org/..." of "Components.classes" fame)???

Thanks!

You need to use legacy code, not WebExtension code.

WebExtension browser.management
http://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/management

Reference
http://searchfox.org/mozilla-release/so ... ement.json
http://searchfox.org/mozilla-release/so ... agement.js

The window.AddonManager object is already available in the browser.xhtml window. (no need to import)

[AlbertG]

morat to the rescue, again

Thanks for unraveling a bit more of this puzzle here...

That said, what might the correct syntax look like for a successful import?

This:

Code: Select all

Components.utils.import("resource://gre/modules/management.jsm");

& this:

Code: Select all

Components.classes["@mozilla.org/management;1"].getService(Components.interfaces.nsISomeBranch);

aren't going to work.

Can't help but wish there was a well-cataloged online repository for this kind of info!

If you want to use the browser.tabs.create function in a script, then you need to examine the create function in the source to see how it works, then produce a legacy equivalent.

Code: Select all

// WebExtension code

(function () {
  browser.tabs.create({
    "url": "http://www.mozillazine.org/",
  });
})();

Code: Select all

// legacy code

(function () {
  gBrowser.addTab("http://www.mozillazine.org/", {
    triggeringPrincipal: Services.scriptSecurityManager.getSystemPrincipal(),
  });
})();

WebExtension browser.tabs
http://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/tabs

Reference

Thanks so much, morat, but this is what I want to import into my autoconfig script scheme:

https://developer.mozilla.org/en-US/doc ... management

I want to explore/use the functions which the "management" API provides:

With the management API you can:

*get information about installed add-ons
*enable/disable add-ons
*uninstall add-ons
*find out which permission warnings are given for particular add-ons or manifests
*get notifications of add-ons being installed, uninstalled, enabled, or disabled.

And this way of doing the "import" into my autoconfig script,

Code: Select all

Components.utils.import("resource://gre/modules/management.jsm");

...doesn't work (of course); and I can't seem to be able to figure the situation out by rummaging through everything in omni.ja

Just need to know what the formatting/syntax would look like to bring this to life

[AlbertG]

morat,

Looking over this thread again, it seems as though I missed some of what you were getting across. Overtired, I guess...

If I now understand the gist of this all correctly, it appears that a generic import for overall "management" functionality into an autoconfig script is not really possible. And, parsing the "management.json" and "ext-management.js" code into intelligible chunks per function is well beyond the pale for my level of mastery at this stage

I'll rummage about and see if there's a more "accessible" way of achieving my purposes; and get back if another question arises

Have a great weekend --

You need to know how to do asynchronous programming to use the AddonManager object.

These code snippets work in the browser console.

Instructions:

* open about:config page
* set devtools.chrome.enabled preference to true
* open browser console i.e. tools > web developer > browser console
* copy and paste code into browser console command line
* press enter to run

Code: Select all

(function () {
  function resolveAfter2Seconds() {
    return new Promise(function (resolve) {
      setTimeout(function () { resolve("resolved"); }, 2000);
    });
  }
  async function example() {
    console.log("calling");
    var result = await resolveAfter2Seconds();
    console.log(result);
  }
  example();
})();

Code: Select all

(function () {
  async function test() {
    var addons = await AddonManager.getAddonsByTypes(["extension"]);
    addons.forEach(function (addon) {
      if (addon.hidden == false && addon.isSystem == false) {
        console.log("Name: " + addon.name + ", Id: " + addon.id + ", Disabled: " + addon.userDisabled);
        console.log(addon);
      }
    });
  }
  test();
})();

Async function
http://developer.mozilla.org/docs/Web/J ... c_function

AddonManager
http://developer.mozilla.org/docs/Mozil ... donManager
http://developer.mozilla.org/docs/Mozil ... ager/Addon

You can use the addon.userDisabled property to disable addons.

[AlbertG]

Thank you, morat, once again for your generous assistance. I guess I'll wind up getting a knack for this after all

Duties call me away for a bit now, but I will dig into this with purpose soon...

Until next time,
Cheers!

[AlbertG]

Hi there, morat. Back again after digging in to the syntax for a bit

In that venture, I wanted to start by running and experimenting with your code samples.

So, I took this first example from your last post and just ran it:

Code: Select all

(function () {
  function resolveAfter2Seconds() {
    return new Promise(function (resolve) {
      setTimeout(function () { resolve("resolved"); }, 2000);
    });
  }
  async function example() {
    console.log("calling");
    var result = await resolveAfter2Seconds();
    console.log(result);
  }
  example();
})();

Looks like it did what it was supposed to, with a few errors. Here's what the console returned:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
uncaught exception: Error in asyncStorage.setItem():
calling debugger eval code:8:13
undefined
resolved debugger eval code:10:13

Upon running your next example,

Code: Select all

(function () {
  async function test() {
    var addons = await AddonManager.getAddonsByTypes(["extension"]);
    addons.forEach(function (addon) {
      if (addon.hidden == false && addon.isSystem == false) {
        console.log("Name: " + addon.name + ", Id: " + addon.id + ", Disabled: " + addon.userDisabled);
        console.log(addon);
      }
    });
  }
  test();
})();

The console returned:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
uncaught exception: Error in asyncStorage.setItem():
undefined
Name: {extension 1}, Id: {id 1}, Disabled: true debugger eval code:6:17
Object { }
debugger eval code:7:17
Name: {extension 2}, Id: {id 2}, Disabled: false debugger eval code:6:17
Object { }
debugger eval code:7:17
Name: {extension 3}, Id: {id 3}, Disabled: false debugger eval code:6:17
Object { }
debugger eval code:7:17
Name: {extension 4}, Id: {id 4}, Disabled: false debugger eval code:6:17
Object { }
debugger eval code:7:17

Similar errors, but ran OK!

Since you mentioned the the addon.userDisabled property, I thought I'd give this a quick run to do something practical. Here's what I came up with:

Code: Select all

(function () {
  async function test() {
    var addons = await AddonManager.getAddonsByTypes(["extension"]);
    addons.forEach(function (addon) {
      if (addon.hidden == false && addon.isSystem == false) {
   addon.userDisabled = true;
        console.log("Name: " + addon.name + ", Id: " + addon.id + ", Disabled: " + addon.userDisabled);
        console.log(addon);
      }
    });
  }
  test();
})();


It's just your previous (working) example with a sandwiched "userDisabled" call

No dice with "userDisabled". The console burped back:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
IndexedDB UnknownErr: ActorsParent.cpp:4588
uncaught exception: Error in asyncStorage.setItem():
undefined
Name: {extension 1}, Id: {id 1}, Disabled: false debugger eval code:7:17
Object { }
debugger eval code:8:17
Name: {extension 2}, Id: {id 2}, Disabled: false debugger eval code:7:17
Object { }
debugger eval code:8:17
Name: {extension 3}, Id: {id 3}, Disabled: false debugger eval code:7:17
Object { }
debugger eval code:8:17
Name: {extension 4}, Id: {id 4}, Disabled: false debugger eval code:7:17
Object { }

Not to be dissuaded from another go, I scratched my head a couple of times, dug around, and came up with this variant -- not expecting too much:

Code: Select all

(function () {
  async function test() {
    let addons = AddonManager.getAddonsByTypes();
    addons.forEach((addon) => { AddonManager.addon.userDisabled(addon.id, true); });
  }
  test();
})();

And I got what I expected! Here's the console's eulogy:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
undefined
uncaught exception: Error in asyncStorage.setItem():
TypeError: addons.forEach is not a function
debugger eval code:4:12

Seeing how that wasn't bearing the fruit generally hoped for, I decided to look about and find pre-fabbed operational code with "userDisabled" functionality here-and-there.

This looked nifty:

Code: Select all

Cu.import('resource://gre/modules/AddonManager.jsm');
AddonManager.getAddonByID('{extension id 4}', function(addon) {
  if (addon.userDisabled) {
       //enable it
       addon.userDisabled = false;
  } else {
       //disable it
       addon.userDisabled = true;
  }
});

The console disgreed:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
Promise { <state>: "pending" }

uncaught exception: Error in asyncStorage.setItem():

( source: https://stackoverflow.com/questions/266 ... fox-addons )

One more try, this one from MDN directly:

Code: Select all

Components.utils.import("resource://gre/modules/AddonManager.jsm");

let addonIDs = AddonManager.getStartupChanges(AddonManager.STARTUP_CHANGE_DISABLED);
if (addonIDs.length > 0) {
  // addonIDs is now an array of the add-on IDs that have been disabled
alert("Note: " + addonIDs.length + " add-ons have been disabled.");
}

Console:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
IndexedDB UnknownErr: ActorsParent.cpp:4588
NonSyntacticVariablesObject { gStrictCompatibility: false, gFinalShutdownBarrier: {…}, gCheckCompatibility: true, EXPORTED_SYMBOLS: (3) […], formatter: {…}, gUpdateEnabled: false, gBeforeShutdownBarrier: {…}, PREF_EM_CHECK_COMPATIBILITY: "extensions.checkCompatibility.68.10", gStartupComplete: true, AddonManagerInternal: {…}, … }

uncaught exception: Error in asyncStorage.setItem():

( source: https://developer.mozilla.org/en-US/doc ... on_Manager )

Now I'm totally confused: It seems as though anything which runs, throws numerous errors; and, that which should certainly run (public code from MDN and stackoverflow), does nothing but tank completely out...



Thanks again --

EDIT: Code transcription error...

[AlbertG]

One more from the mother wit, just for luck:

Code: Select all

(function () {
    var addons = AddonManager.getAllAddons();
    addons.forEach(function () { addon.userDisabled(true); } );
})();

Output:

IndexedDB UnknownErr: ActorsParent.cpp:4588
IndexedDB UnknownErr: ActorsParent.cpp:13188
TypeError: addons.forEach is not a function
debugger eval code:3:12
uncaught exception: Error in asyncStorage.setItem():

???

Edit: Syntax...

[morat]

I'm not seeing those errors. The problem may be a corrupted profile.

IndexedDB UnknownErr: ActorsParent.cpp
http://bugzilla.mozilla.org/show_bug.cgi?id=1362878
http://bugzilla.mozilla.org/show_bug.cgi?id=1362878#c18

The getAllAddons is an asynchronous method that returns a Promise object.

Code: Select all

(async function () {
  var addons = await AddonManager.getAllAddons();
  addons.forEach(function (addon) {
    console.log(addon.id, addon.type, addon.hidden, addon.isSystem);
  });
})();

Code: Select all

(function () {
  AddonManager.getAllAddons().then(function (addons) {
    addons.forEach(function (addon) {
      console.log(addon.id, addon.type, addon.hidden, addon.isSystem);
    });
  });
})();

Promise

[AlbertG]

Thanks, morat, for coming back...

Ran everything on another identity, and some of the issues seemed to clear.

However, the console returns,

NS_NOINTERFACE: Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface] stack-trace-collector.js:84
Promise { <state>: "pending" }

-- or --

uncaught exception: Error in asyncStorage.setItem():
Promise { <state>: "pending" }

...when running this directly in the console:

Code: Select all

(async function ()
{
   var addons = await AddonManager.getAllAddons();
   addons.forEach(function (addon)
         {
                if (addon.hidden == false && addon.isSystem == false)
               {
                  addon.userDisabled = true;
               }
         });
})();

Of course, the code does nothing

Finally, when attempting to import AddonManager.jsm within an autoconfig setup,

Code: Select all

Components.utils.import("resource://gre/modules/AddonManager.jsm");

...the console returns at browser startup:

NS_ERROR_NOT_INITIALIZED: AddonManager is not initialized AddonManager.jsm:2912

Is this all essentially hopeless?

Thanks again --

[morat]

Well I think you should give up. The userChrome.js hacks are for advanced users and legacy docs are not updated since legacy extensions are obsolete.

You can use the addon.userDisabled property to disable addons.

Sorry, that's wrong. I tested all the code I posted, but I didn't test the userDisabled property. I had to examine the source to figure out the legacy code.

Code: Select all

// disable all non-hidden non-system extensions
// open about:addons to see status change

(async function () {
  var addons = await AddonManager.getAddonsByTypes(["extension"]);
  addons.forEach(function (addon) {
    if (addon.hidden == false && addon.isSystem == false) {
      console.log("Name: " + addon.name + ", Id: " + addon.id);
   // addon.userDisabled = true; // fails
      addon.disable();
    }
  });
})();

[AlbertG]

Well, nuts...

For the record, your new code did run as anticipated from the console. And, calling "addon.enable();" has the expected inverse effect on the installed Add-on collection.

However, running the code from an auticonfig setting with

Code: Select all

Components.utils.import("resource://gre/modules/AddonManager.jsm");

returns the inescapable

NS_ERROR_NOT_INITIALIZED: AddonManager is not initialized AddonManager.jsm:2912

...so I guess this type of thing has been essentially removed from the roster of goodies for this type of scripting.

Here's hoping some of the foregoing will be of use to others in their efforts

Thanks again, and have a great day!

The window.AddonManager object is already available in the browser.xhtml window. (no need to import)
