Mozilla FTP – Download Latest Firefox

Latest (~sort of~ “nightly”) Firefox Developer Edition, Code-Name `Aurora`
https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-aurora/

This is the full offline-installer, not the `installer-stub` you get from the official website.


Latest Nightly-Build from trunk Firefox
https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/

You can download a localised (or “localized”.. if you’re an American..) language-specific version on https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-aurora-l10n/.


Latest Beta
https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-beta-l10n/

It seems that there is no generic package so you must choose one of the localised-packages,
for example https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-beta-l10n/firefox-47.0.en-GB.win64.installer.exe or https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-beta-l10n/firefox-47.0.en-GB.win64.zip


You may also download ESR (extended support release) for latest or not-so latest versions of Firefox, which is mostly useful if you don’t want to keep updating the core-browser’s version a lot..
Version 45: https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-esr45-l10n/
And version 52: https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-esr52-l10n/

Here too, you must choose a localised-download..


Browser https://ftp.mozilla.org/pub/firefox/nightly/ for “by date” downloads or any other variation of Firefox you may download, in-full.
