It only works for all the other protocols. 1. Add a bookmark and enter "javascript:alert("hello world")" as URL 2. give a tag like "js" 3. Goto location bar and enter "js" I expect to see my added bookmark. If you are using a keyword instead it works fine (when searching for the keyword).

Oh, as what I can see too. The autocomplete doesn't work at all for those bookmarks. You don't really have to set a tag.
