When I go to a bookmarked page, I notice that the star on the address line is either all blue, or (as this page I write on) only blue in outline. I have discovered that the blue stars will allow the bookmark to be deleted - but the blue outline stars turn blue on one click, then allow the deleting mechanism to appear, but when you follow this through, the bookmark remains. Question being - how do I delete bookmarks with the outline blue star?
