Rated 5 out of 5 stars

I'm so glad that Bug489729 add-on has been updated to work in FF4! In fact Tab Mix Plus has stopped the inadvertent tearing off of tabs, BUT neither that nor anything other than this add-on appears to enable dragging tabs to the desktop or into other browsers. Thank you for keeping this extremely useful facility available - and for making it so in the first place.

This review is for a previous version of the add-on (1.7.1-signed.1-signed).
