On the https://www.firefox.com/browsers/enterprise/ page there is the "Download Firefox or Firefox ESR for another language or platform" which leads to https://www.firefox.com/download/all/desktop-esr/ which has 64-bit and 32-bit Linux Firefox 140 ESR.

Btw Mozilla has dropped 32-bit Linux support starting Firefox 145.0 and later https://support.mozilla.org/en-US/kb/firefox-has-ended-support-32-bit-linux though Firefox 140.0 ESR is still an option till Fx 140.15.0esr in September 2026.

ESR is short for Extended Support Release as Enterprise IT support staff like longer term stability vs latest version. I think most Enterprise IT admins do support on Windows with some on macOS as to why Linux is omitted on that enterprise page. ESR is not targeted towards regular Firefox users.

The reason it wasn't on the page at the time we built it is because we didn't have any Linux specific documentation or policy stuff.

We'll be redoing that web page soon.

I was wondering the same thing. It seems like the enterprise page mainly highlights Windows and macOS, while Linux users usually download the ESR version directly from the Mozilla FTP. It would definitely be helpful if the Linux option was listed more clearly on the enterprise page.

As I posted "On the https://www.firefox.com/browsers/enterprise/ page there is the "Download Firefox or Firefox ESR for another language or platform" link which leads to https://www.firefox.com/download/all/desktop-esr/ which has 64-bit and 32-bit Linux Firefox 140 ESR."

Btw there is no more Mozilla ftp as the ftp used to be ftp://ftp.mozilla.org until Mozilla disabled the ftp:// protocol on ftp.mozilla.org back on August 5th, 2015. Also the desktop Firefox does not view ftp:// anymore as of Fx 90.0. Mozilla also prefers you use https://archive.mozilla.org over https://ftp.mozilla.org
