Obviously I have Firefox installed as a backup browser -- see screenshot image. While I used Firefox as my primary browser on my old Mac, I see no good reason to not use Safari on the new Mac.
Maybe I'm the only one, who makes use of the "show properties" feature, if available, but I have my reasons for using it. Downloading graphics is exactly what I don't want to do without first checking "properties." I simply figured the feature was hidden in Safari.
Honestly I only used Safari a few times, I use Firefox as my primary browser. I rarely every use the right click to see properties or in mac language is hold either apple/command or control then click. I think Safari is made to be simple, I don't know if its similar to Netscape or something like that. Make a suggestion to Apple, maybe they will add that to their next update of Safari.
