Sometimes you might need to include changes you've made to Firefox in a new installer. This might be a policies.json file, AutoConfig changes or extensions. This document shows how to do that. =Step One= Download the installer that you want to repackage. Make sure you download a full installer and not a stub installer. The stub installer is typically named "Firefox Installer.exe" whereas the full installer is named "Firefox Setup VERSION.exe." You can download full installer of Firefox ESR from [https://www.mozilla.org/firefox/organizations/all/ here] and of rapid release from [https://www.mozilla.org/firefox/all/ here]. =Step Two= Unzip the installer into a directory. You'll need to use [https://www.7-zip.org/ 7-zip] in order to unzip it. 7z x "Firefox Setup VERSION.exe" =Step Three= Make your changes to Firefox in the core subdirectory. =Step Four= Repackage Firefox by running this command in the directory where you unzipped Firefox. 7z a -r -t7z app.7z -mx -m0=BCJ2 -m1=LZMA:d24 -m2=LZMA:d19 -m3=LZMA:d19 -mb0:1 -mb0s1:2 -mb0s2:3 This will create a file called app.7z that contains the changes. =Step Five= Download the files [https://hg.mozilla.org/mozilla-central/raw-file/tip/other-licenses/7zstub/firefox/7zSD.sfx 7zSD.sfx] and [https://hg.mozilla.org/mozilla-central/raw-file/tip/browser/installer/windows/app.tag app.tag] and save them in the same directory where the app.7z is located. =Step Six= Run this command: copy /B 7zSD.sfx+app.tag+app.7z our_new_installer.exe to concatenate the files and create the installer. The “/B” is very important! It tells copy that these are binary files so it doesn’t add extra characters to the files.
