Duplicate Question Suggestion Boxes is a UserScript for any Stack Exchange site that makes it extremely simple to check for duplicate questions for a post. In the left side it shows the duplicate question suggestions right under the title (the one you get when you ask the question) and in the right side it shows the related questions (moved from the sidebar).

When you click on a link, it opens the duplicate question close box. You can then easily click through the questions and view them all in the open duplicate question close box. This makes finding the right duplicate (if one exists) blazingly fast except for those weird cases where you need to visit the search...

  • 1.1.1: Small graphical fixes for Google Chrome, proper clear:both and removed element focus.

  • 1.1: Links now open the duplicate question close box and also get trimmed after 60 characters.

    Title was placed under the boxes instead of above it so it fits together with the question body.

  • 1.0: Script released to the public, two boxes that just have links to the question pages.


  • When there comes a future release, I will implement an update check for convenience.

  • Interface improvements, there is some real estate stolen. How could this be fixed?

  • Do you have any ideas to be implemented?

  • @GeorgeEdison what happened to it? Sounded so promising :) Commented Oct 21, 2012 at 21:05

    @BrunoPereira: It's still there - I just made some changes to my website such that URLs ending in '/' are no longer accepted. I fixed the link in the post above. Commented Oct 21, 2012 at 21:50

    hey @Tom, the script seems to be a bit broken off late, can you take a look? i.imgur.com/KxzrEZ3.png Commented Mar 23, 2013 at 14:26
  • It no longer works. Are there alternatives?

I've been a long time user of this script and really loved it.

The makeover is excellent, 1-click vote is pretty nice!

Some minor issues:

On Stack Overflow: Notice that the starting letter of the question("I") is still at the top


I stuck at top

Seems to happen at cases where the question length exceeds certain limit


But this is fine:

Meta has the same cut-off problem

  • This has been resolved now, apparently Google Chrome acted different but actually more correct. Commented Dec 14, 2011 at 12:46
