If you are using the Mozilla Firefox web browser and have the Greasemonkey extension for it installed, then the button should appear when viewing the main Google search page. It will not appear when search results are displayed. I am not sure if it will work with other web browsers, as I have not been able to test it with other browsers.

I have found that it works with Firefox when Greasemonkey is used with it. I have also found that it works when Google.com is viewed. The latest version of it, which can be downloaded from here, has worked for me, and no other users of the script have informed me of any difficulties with it.

If you have any other questions or can provide me with any other information that may be useful, then you may reply to this comment.

Thanks,

J.K.
