I highly doubt that the author of this extension cares but I sorta got it working again.
But you should only do the following steps if you accept all the RISKS!!!

I downloaded Edit As New
Then renamed the file name extension from .xpi to .zip
Now I can double click that file and Windows will open it.
I found a file inside called install.rdf I right-clicked it and chose copy.
Then I went back and next to the zip file I pasted install.rdf.
I opened it with notepad and looked for "em:maxVersion"
Once I found them I changed the number to ">3.9.*<"
Saved then closed Notepad, then dragged and dropped install.rdf on the zip file.
Said yes when asked to overwrite and save the changes to the zip file.
Then renamed the file name extension from .zip to .xpi

It seems to be working fine for me under WinXP2 w/TBird3.1.6

It is unfortunate that the author seems to have abandon this addon. It is great for those emails with attachments that we need to send on to a 3rd person, but don't want to mess with re-attaching files, etc.
