Sounds good. This question has so many suggestions and half of them are useless and may actually cause issues. It is best to open a new thread. That way people helping have a better idea of what has been done.
Google chrome is pretty bad in general. They open a new instance of chrome for each tab and they end up using way to much memory. IE is actually more secure. It is a little technical why but they have some better protection for XSS attacks as well as a new feature rolled out last July and August that protects the pieces of memory that are waiting to be garbage collected (since memory items don't delete when you are done they are still present until that memory space is needed which is in short garbage collecting)
But that is sometime a personal preference. You can read more about security in the IBM security intelligence web site.
