Projects
Fixing nsIProcess
Project page: Fixing nsIProcess
The API in Firefox for managing external processes has never been fully implemented. This project aims to implement the existing API and extend the API to include inter-process communication.
The Canvas 3D JS Libary (C3DL)
Project page: C3DL
C3DL is a javascript library that will make it easier to write 3D applications using canvas 3d. It will provide a set of math, scene, and 3d object classes to make the canvas more accessible for developers that want to develop 3D content in browser.
Mozilla Developer Resource Kit
Project page: Mozilla Developer Resource Kit
Creating a package that contains everything a developer needs, including documentation, to get started with Firefox. The plan is to make it available as a live Fedora DVD for developers in countries where bandwidth is scarce.
Portable DXR
Project page: Portable DXR
This is closely related to the MDRK. The aim is to package the Mozilla developer documentation and the DXR source browsing tool in an extension that can be easily distributed/installed mostly likely as a XUL/Prism application. As an added bonus, this is a group project where the team members are experimenting with using traditional project planning tools and open source development methods.
Software
Process Manager Extension
A binary XPCOM extension that allows processes external to Firefox to be started and stopped. Currently only Win32 is supported. It is used in the SHTTPD extension.
Further notes on usage: http://jamesboston.ca/cms/node/41
Download: http://jamesboston.ca/extensions/processmanager.xpi

SHTTPD Extension
This is a proof of concept. Installing this extension will start a tiny webserver that runs locally. The purpose of this is to eventually provide a way to distribute web application as extensions so they can be run locally/offline. At present, when the browser starts the server also starts and installs an icon to the system tray. It only runs on Win32 machines.
Download: http://jamesboston.ca/extensions/shttpd.xpi
(The server is licensed as beerware and is available on its own at http://shttpd.sourceforge.net/).
Open in Editor Extension
This extension will open source code files from http://mxr.mozilla.org in an editor on the users machine. Simply right click on the loaded page and select the Open in Editor option from the pop up context menu. The user may choose any editor through preference settings. If no preferences are selected the extension defaults to gedit on Linux, notepad on Windows, and (currently) nothing on OS X.

Ubiquity commands
Building Firefox
Install prerequisites
Windows
Install Visual Studio:
(The express version will work.)
http://msdn2.microsoft.com/en-us/vstudio/aa700736.aspx
Get Microsoft Windows Software Development Kit Update for Windows Vista (even if you are using XP):
http://www.microsoft.com/downloads/details.aspx?FamilyID=4377f86d-c913-4b5c-b87e-ef72e5b4e065&DisplayLang=en
Download and install Mozilla Build, a package of software prerequisites:
(If you get a message saying this application did not install properly then you should see a windows dialog giving you the option to re-install with the 'correct settings'. After that all should be well.)
http://ftp.mozilla.org/pub/mozilla.org/mozilla/libraries/win32/MozillaBuildSetup-1.3.exe
To open a shell window click (right-click for admin privileges on Vista):
c:\mozilla-build\start-msvc8.bat
(The example above is for Visual Studio 2005. The name of the bat file you use should match the directory that Visual Studio is installed in.)
Linux
Install build pre-requisites for Fedora 10 users:
su -c "yum groupinstall 'Development Tools' 'Development Libraries' 'GNOME Software Development'" su -c "yum install mercurial autoconf213 libXt-devel"
Install Firefox 3 build re-requisites for Ubuntu 8.10 users:
sudo apt-get install build-essential sudo apt-get build-dep firefox sudo apt-get install mercurial libasound2 libasound2-dev curl libcurl4-gnutls-dev
You may need to set an environment variable if the build system can't find autoconf:
export AUTOCONF=autoconf2.13
OS X
In order to build Firefox you will need something called MacPorts which can be dowloaded from here:
http://www.macports.org/install.php
After downloading and installing MacPorts you can then install the pre-requisites:
sudo port sync sudo port install mercurial libidl autoconf213
Configuration
You need to create a hidden file for the build system that contains instructions on how you want your build completed.
Create and open a hidden file called .mozconfig in your home directory using notepad or vim:
notepad.exe ~/.mozconfig
Add the following lines to .mozconfig
# My first mozilla config . $topsrcdir/browser/config/mozconfig mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-@CONFIG_GUESS@ ac_add_options --disable-optimize ac_add_options --enable-debug
If you are using a multi-core computer for building, you can try adding a flag to speed up compile times. Use a value of ((# of cores)*2)+1 (ie. five for two cores):
mk_add_options MOZ_MAKE_FLAGS=-j5
For OS X (Leopard) add:
ac_add_options --with-macos-sdk=/Developer/SDKs/MacOSX10.5.sdk
For Windows XP it may be necessary to add the following additional line to your .mozconfig file:
ac_add_options --disable-vista-sdk-requirements
Visual Studio 2008 users may also need to add one or more of the following to .mozconfig:
ac_add_options --disable-xpconnect-idispatch ac_add_options --disable-activex ac_add_options --disable-activex-scripting ac_add_options --disable-accessibility ac_add_options --disable-parental-controls
Getting the source
If you are attempting to build Firefox 3.1 or greater you can checkout the source using mercurial as described below. When creating a working directory and checking out the source it doesn't really matter where you put it, but avoid paths that contain spaces. Spaces in the path name will cause the build to fail. For Windows XP users, your home directory path almost certainly has spaces. If that is the case, just put the mozilla directory in your root (ie. C:\mozilla) and put the .mozconfig file in that directory. If your user name doesn't have space you can checkout the source to your home directory like this:
cd mkdir mozilla cd mozilla hg clone http://hg.mozilla.org/mozilla-central/ src
It is still possible to checkout older versions of Firefox using cvs:
cd cvs -d :pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co mozilla/client.mk cd ~/mozilla make -f client.mk checkout MOZ_CO_PROJECT=browser
Starting the build
You need to change to the directory that contains the source code and then run the make command:
cd ~/mozilla/src time make -f client.mk build
Running the build
Once the build is finished you should set the following environment variable to turn-off assertion dialogs:
export XPCOM_DEBUG_BREAK=warn
When you run your build for the first time, create and select a new profile called "development" (or any name of your choice) to avoid corrupting your current profile.
Windows and Linux:
~/mozilla/src/obj*/dist/bin/firefox -profilemanager
OS X:
~/mozilla/src/obj*/dist/MinefieldDebug.app/Contents/MacOS/firefox
Updating a build
If you need to refresh the source code:
cd ~/mozilla/src hg pull -u
Rebuilding the browser
If you want to rebuild the entire browser just repeat the instructions for starting the build above. However, it is possible to do incremental builds where only the source code you have changed is compiled.
For instance, to rebuild after a change in the xpcom module try:
make -C ~/mozilla/src/obj*/xpcom
Or as a more general form:
make -C [the object directory corresponding to the source directory that has changed]
In most cases this will relink the changes and create a new browser binary. But there's not hard and fast rule about when you can successfully do an incremental build. Sometimes you can burrow a few levels into the object tree and sometime you need to build from the very top. It may take a bit of trial and error to discover what works.
Tunneling a VNC session
One of the Mac minis in the ORI area is configured to accept VNC connections, but without an SSH tunnel it's too slow to be useful. These instructions will help you get setup.
