I think #23 (View Source: View the syntax coloured source of a page, without having to view it in Notepad) isn't particularly a feature. You can't do anything with the 'view source'-option of Mozilla other than view. In IE, besides viewing you can edit the document and save it locally.
I like both Mozilla and IE. But Mozilla isn't safe of vulnerabilities, see http://www.theregister.co.uk/content/55/27934.html and http://www.mozilla.org/projects/security/known-vulnerabilities.html

True, but I think Moz bugs get fixed quicker.
