Please update for IE9, (but manual fix works ok) Rated 5 out of 5 stars
For IE9 use: I can verify that the fix offered below by user "Andrew" works well. Thank you.
This is a great extension that I used a lot in IE8. (With this manual fix I can finally use it in IE9 until the author officially updates this Add-on for Internet Explorer 9 compatibility, (hopefully!).)
