Drag&Drop menu is back

Three years ago I wrote to the forum for help with a “strange popup” that was causing me problems. It turned out to be a feature called Comodo Drag&Drop Service and it could be deactivated under Extensions. Now it’s back and it’s not under Extensions anymore. Can it be turned off? (It blocks me from dragging and dropping messages in my folders in Yahoo Mail.)

All right, found a solution under the heading Sidebars. Adding on yet another add-on to shut off a feature. Great. But it worked.
