Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including mupee with all npm packages installed. Try it out:

mupee lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("mupee/[??]")

mupee v1.0.1

Mupee is a proxy between the update servers and your corporate Mozilla software.

Mozilla Updater


Mupee acts as a proxy between the update servers and your corporate Mozilla software. Using it, you can allow/deny updates of Mozilla products per version. As an example, you can tell Mupee to allow updates of Thunderbird up to the last minor version of the 17 branch, but not switch to the 24 branch.


Mozilla updater proxy needs:

  • node.js version >= 0.10.x
  • a MongoDB server
  • an internet connection to the Mozilla update servers

How to use it

    npm install mupee
    cd node_modules/mupee
    npm start

It will start the server with some default values (1234 as the server port or 27017 as the mongodb server port).

On your Mozilla softwares (Thunderbird and Firefox), add a setting :

app.update.url.override=http://[your proxy IP address or hostname]/update/3/%PRODUCT%/%VERSION%/%BUILD_ID%/%BUILD_TARGET%/%LOCALE%/%CHANNEL%/%OS_VERSION%/%DISTRIBUTION%/%DISTRIBUTION_VERSION%/update.xml

How to configure it

Rename ./conf/config.json.sample to ./conf/config.json.

Here's the details :

      "download" : {
        "dir" : "./data/files",                               // default path to store mozilla updates.
        "autoCache" : true                                    // not implemented yet
      "database" : {
        "url" : "mongodb://localhost:27017/mozilla-updater",  // mongodb server location
        "options" : {                                         // options for the mongodb driver
          "auto_reconnect" : true,

      "server" : {
        "port" : 1234,                                       // default node server port
        "url" : "http://localhost"
      "log" : {                                              // loggin options
        "file" : {
          "enabled" : true,
          "filename" : "./log/mozilla-updater.log",
          "level" : "info",
          "handleExceptions" : true,
          "json" : false,
          "prettyPrint" : true,
          "colorize" : false
        "console" : {
          "enabled" : true,
          "level" : "debug",
          "handleExceptions" : true,
          "json" : false,
          "prettyPrint" : true,
          "colorize" : true
