There are two common ways to obtain a +MAR to use: download a prebuilt one, or build one yourself. + +Downloading a MAR +~~~~~~~~~~~~~~~~~ + +Prebuilt Nightly MARs can be found +`here <https://archive.mozilla.org/pub/firefox/nightly/>`__ on +archive.mozilla.org. Be sure that you use the one that matches your +machine's configuration. For example, if you want the Nightly MAR from +2019-09-17 for a 64 bit Windows machine, you probably want the MAR +located at +https://archive.mozilla.org/pub/firefox/nightly/2019/09/2019-09-17-09-36-29-mozilla-central/firefox-71.0a1.en-US.win64.complete.mar. + +Prebuilt MARs for release and beta can be found +`here <https://archive.mozilla.org/pub/firefox/releases/>`__. Beta +builds are those with a ``b`` in the version string. After locating the +desired version, the MARs will be in the ``update`` directory. You want +to use the MAR labelled ``complete``, not a partial MAR. Here is an +example of an appropriate MAR file to use: +https://archive.mozilla.org/pub/firefox/releases/69.0b9/update/win64/en-US/firefox-69.0b9.complete.mar. + +Building a MAR +~~~~~~~~~~~~~~ + +Building a MAR locally is more complicated. Part of the problem is that +MARs are signed by Mozilla and so you cannot really build an "official" +MAR yourself. This is a security measure designed to prevent anyone from +serving malicious updates. If you want to use a locally-built MAR, the +copy of Firefox being updated will need to be built to allow un-signed +MARs. See :ref:`Building Firefox <Firefox Contributors' Quick Reference>` +for more information on building Firefox locally. In order to use a locally +built MAR, you will need to put this line in the mozconfig file in root of the +build directory (create it if it does not exist): + +.. code:: + + ac_add_options --enable-unverified-updates + +Firefox should otherwise be built normally. After building, you may want +to copy the installation of Firefox elsewhere. If you update the +installation without moving it, attempts at further incremental builds +will not work properly, and a clobber will be needed when building next. +To move the installation, first call ``./mach package``, then copy +``<obj dir>/dist/firefox`` elsewhere. The copied directory will be your +install directory. + +If you are running Windows and want the `Mozilla Maintenance +Service <https://support.mozilla.org/en-US/kb/what-mozilla-maintenance-service>`__ +to be used, there are a few additional steps to be taken here. First, +the maintenance service needs to be "installed". Most likely, a +different maintenance service is already installed, probably at +``C:\Program Files (x86)\Mozilla Maintenance Service\maintenanceservice.exe``. +Backup that file to another location and replace it with +``<obj dir>/dist/bin/maintenanceservice.exe``. Don't forget to restore +the backup when you are done. Next, you will need to change the +permissions on the Firefox install directory that you created. Both that +directory and its parent directory should have permissions preventing +the current user from writing to it. + +Now that you have a build of Firefox capable of using a locally-built +MAR, it's time to build the MAR. First, build Firefox the way you want +it to be after updating. If you want it to be the same before and after +updating, this step is unnecessary and you can use the same build that +you used to create the installation. Then run these commands, +substituting ``<obj dir>``, ``<MAR output path>``, ``<version>`` and +``<channel>`` appropriately: + +.. code:: bash + + $ ./mach package + $ touch "<obj dir>/dist/firefox/precomplete" + $ MAR="<obj dir>/dist/host/bin/mar.exe" MOZ_PRODUCT_VERSION=<version> MAR_CHANNEL_ID=<channel> ./tools/update-packaging/make_full_update.sh <MAR output path> "<obj dir>/dist/firefox" + +For macOS you should use these commands: + +.. code:: bash + + $ ./mach package + $ touch "<obj dir>/dist/firefox/Firefox.app/Contents/Resources/precomplete" + $ MAR="<obj dir>/dist/host/bin/mar.exe" MOZ_PRODUCT_VERSION=<version> MAR_CHANNEL_ID=<channel> ./tools/update-packaging/make_full_update.sh <MAR output path> "<obj dir>/dist/firefox/Firefox.app" + +For a local build, ``<channel>`` can be ``default``, and ``<version>`` +can be the value from ``browser/config/version.txt`` (or something +arbitrarily large like ``2000.0a1``). + +.. container:: blockIndicator note + + Note: It can be a bit tricky to get the ``make_full_update.sh`` + script to accept paths with spaces. + +Serving the update +------------------ + +Preparing the update files +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +First, create the directory that updates will be served from and put the +MAR file in it. Then, create a file within called ``update.xml`` with +these contents, replacing ``<mar name>``, ``<hash>`` and ``<size>`` with +the MAR's filename, its sha512 hash, and its file size in bytes. + +:: + + <?xml version="1.0" encoding="UTF-8"?> + <updates> + <update type="minor" displayVersion="2000.0a1" appVersion="2000.0a1" platformVersion="2000.0a1" buildID="21181002100236"> + <patch type="complete" URL="http://127.0.0.1:8000/<mar name>" hashFunction="sha512" hashValue="<hash>" size="<size>"/> + </update> + </updates> + +If you've downloaded the MAR you're using, you'll find the sha512 value +in a file called SHA512SUMS in the root of the release directory on +archive.mozilla.org for a release or beta build (you'll have to search +it for the file name of your MAR, since it includes the sha512 for every +file that's part of that release), and for a nightly build you'll find a +file with a .checksums extension adjacent to your MAR that contains that +information (for instance, for the MAR file at +https://archive.mozilla.org/pub/firefox/nightly/2019/09/2019-09-17-09-36-29-mozilla-central/firefox-71.0a1.en-US.win64.complete.mar, +the file +https://archive.mozilla.org/pub/firefox/nightly/2019/09/2019-09-17-09-36-29-mozilla-central/firefox-71.0a1.en-US.win64.checksums +contains the sha512 for that file as well as for all the other win64 +files that are part of that nightly release). + +If you've built your own MAR, you can obtain its sha512 checksum by +running the following command, which should work in Linux, macOS, or +Windows in the MozillaBuild environment: + +.. code:: + + shasum --algorithm 512 <filename> + +On Windows, you can get the exact file size in bytes for your MAR by +right clicking on it in the file explorer and selecting Properties. +You'll find the correct size in bytes at the end of the line that begins +"Size", **not** the one that begins "Size on disk". Be sure to remove +the commas when you paste this number into the XML file. + +On macOS, you can get the exact size of your MAR by running the command: + +.. code:: + + stat -f%z <filename> + +Or on Linux, the same command would be: + +.. code:: + + stat --format "%s" <filename> + +Starting your update server +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Now, start an update server to serve the update files on port 8000. An +easy way to do this is with Python. Remember to navigate to the correct +directory before starting the server. This is the Python2 command: + +.. code:: bash + + $ python -m SimpleHTTPServer 8000 + +or, this is the Python3 command: + +.. code:: bash + + $ python3 -m http.server 8000 + +.. container:: blockIndicator note + + If you aren't sure that you started the server correctly, try using a + web browser to navigate to ``http://127.0.0.1:8000/update.xml`` and + make sure that you get the XML file you created earlier. + +Installing the update +--------------------- + +You may want to start by deleting any pending updates to ensure that no +previously found updates interfere with installing the desired update. +You can use this command with Firefox's browser console to determine the +update directory: + +.. code:: + + ChromeUtils.importESModule("resource://gre/modules/FileUtils.sys.mjs").FileUtils.getDir("UpdRootD", [], false).path + +Once you have determined the update directory, close Firefox, browse to +the directory and remove the subdirectory called ``updates``. + +| Next, you need to change the update URL to point to the local XML + file. This can be done most reliably with an enterprise policy. The + policy file location depends on the operating system you are using. +| Windows/Linux: ``<install dir>/distribution/policies.json`` +| macOS: ``<install dir>/Contents/Resources/distribution/policies.json`` +| Create the ``distribution`` directory, if necessary, and put this in + ``policies.json``: + +:: + + { + "policies": { + "AppUpdateURL": "http://127.0.0.1:8000/update.xml" + } + } + +Now you are ready to update! Launch Firefox out of its installation +directory and navigate to the Update section ``about:preferences``. You +should see it downloading the update to the update directory. Since the +transfer is entirely local this should finish quickly, and a "Restart to +Update" button should appear. Click it to restart and apply the update. |
