This of course will be useful since many users these days are trying alternatives to IE. I'd also like to add that there is a need to be able to protect MULTIPLE homepages. In IE, Firefox, Google, and Safari (not sure of others) you can have multiple home pages. SAS does protects the 1st homepage listed in IE, if more than 1 is entered, but it does not block or warn if the additional home pages are changed or removed.
Keep up the good work - 5.0 has some great new features
PS I know this is a reply to somewhat of an old post (I have seen at least 1 other with same request for other use with other browsers, but I think this one is most recent) but, I think my suggestion is better mentioned as an addition to this suggestion, instead of standing off on it own)
