From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.7) Gecko/20011226 BuildID: 2001122617 In Xwindows/Linux, selecting text copies it to the clipboard. This is troublesome when trying to copy/paste URL's into the URL bar since selecting the URL in the URL bar with the intention of deleting it overwrites any URL you have in the clipboard waiting to paste. Konqueror gets around this problem by placing a small button next to the bar that clears the bar and sets the focus/cursor into the bar without ever selecting the text. Thus, the clipboard is not overwritten and you are ready to paste. This would be a very handy feature for anyone that uses Mozilla in X-windows.

Just a note. middle-mouse-pasting a url into the content area will load that url (so there is no reason to put it in the url bar to start with).
