This could be about a new security feature that blocks unsafe downloads, but can interfere with downloading files. You can set dom.block_download_insecure => false in about:config to disable this feature.

This will be reverted in an upcoming Firefox 125.0.2 release.

Yess but...what if i want only 1 or 2 or certain websites to be in the "Allow" list for this issue...because, by disabling "dom.block_download_insecure" , we kind of make a "BackDor" for real Potential security risk from any other websites.

For example, my users are not so careful when they receive an email, through Zimbra (mx.MYWEBMAIL.com), and click on that link that redirects them to a file received externally...

I would love to have, in the next update, the option to be able to add a site to the trusted ones, so I don't get the "File not downloaded. Potential security risk." message anymore, but for that particularly site that I add in the list :)

You don't need to disable dom.block_download_insecure anymore with version 125.0.2, it will continue to warn about insecure downloads on secure sites but not on insecure sites like before.

The intention is for private networks to be excluded (Bug 1892011).
