I needed to reinstall Firefox on this computer, so I started up Chrome to download the latest version and it blocked the download as unsafe! I had to manually tell it to download anyway.
Fuck Chrome. I’m glad I only used it to download one file and went back to Firefox.
Where did you get the installer from? I can’t reproduce that problem on my machine.
Unless you mean the warning that applies to all executable files (“this file type could be dangerous”) but that’s just basic security that Firefox also (should) have.
