the above menu item appears in a drop down menu when I right click on a URL I pasted in an new email I am composing. I am curious as to what AtD is. I cannot locate any info on it at support.mozilla.com or Google. This is not an urgent issue, just curious as to what it is, and what the results are by clicking it on or off.

Found ! (thanks google)

AtD is for "After the Deadline", which is a spell checking extension.

I remember installing this extension now !

I totally agree that they use a very strange and confusing name ^^
