Use the encodeURIComponent to turn spaces into "+", mask control characters and punctuation, etc.

javascript:{alert(encodeURIComponent(document.title)+" \n"+encodeURIComponent(location.href)) ;}

  Firefox%20Customizations%20(Notes) 
  http%3A%2F%2Fwww.mvps.org%2Fdmcritchie%2Ffirefox%2Ffirefox.htm%23ext_table

javascript:{alert(document.title+" \n"+location.href) ;}

  Rendered as follows:
  Firefox Customizations (Notes) 
  http://www.mvps.org/dmcritchie/firefox/firefox.htm#ext_table

javascript:{alert(encodeURIComponent(location)+" \n"+location) ;}

  The rendition of the last one in test version might look like this
  file%3A%2F%2F%2Fc%3A%2Fcopiedsite%2Fdmcritchie%2Ffirefox%2Fjavascript.txt 
  file:///c:/copiedsite/dmcritchie/firefox/javascript.txt
