Hi,

I used www.virustotal.com site to scan this firefox file. https://ftp.mozilla.org/pub/firefox/releases/57.0.2/win32/en-GB/Firefox%20Setup%2057.0.2.exe The antivirus Cylance it says "unsafe" . Is tha false? Because Firefox is known for privacy and security.

Thank you

No it is not. First is a FTP site, most people now do not know anything about them or why. This the Full Version Installer link same as above : If in need of the Extended Release Version 52.5.2 ESR : Please let us know if this solved your issue or if need further assistance.

Yes I know it's FTP. I downloaded from both sites and the file is exactly the same. Size name etc.. What's the difference?

Actually there is no FTP anymore as the ftp:// protocol was retired by Mozilla since Aug 5, 2015. So downloading from ftp://ftp.mozilla.org with a browser or ftp client no longer works.

It leads to same build yes. Mozilla uses a CDN to deliver the downloads. They used to use a mirrors system which meant you could be getting directed to a different mirror each time you downloaded say a Firefox release.

What is listed on www.mozilla.org/firefox/all/ is in for example https://ftp.mozilla.org/pub/firefox/releases/ http://archive.mozilla.org/pub/firefox/releases/ http://download-origin.cdn.mozilla.net/pub/firefox/releases/

The setup from you link did result in Cylance being the only one to claim unsafe for Ad-Aware. https://www.virustotal.com/#/file/1c4bbdd279263c6ca7501930149a58341b4cac933ebcc329756810a4090f7235/detection

Happen to find a virustotal result from August where Cylance was again the only one that claimed unsafe. https://virustotal.com/en/file/1e7e52a0b3fd65fdd378da7b879cb808b99e10718acfa157c4eabffb7ca596ea/analysis/1502906203/

Some antivirus clients do result in false positives with Firefox on Windows, which is more likely occur after a recent new major Firefox version or update but not later on with same version.

While this was a full Firefox setup for Windows, some antivirus clients have done false positives on the small online stub installers served on www.mozilla.org (for Windows users) every so often even though it had been in use since Firefox 18.0.

Thank you for the information. So in either of these directories leads to the same files that were Uploaded by Mozilla and it is safe to use? The installers of the site www.mozilla.org/firefox/all/

leads to the directory

https://download-installer.cdn.mozilla.net/pub/firefox/releases/
