How would I sign a firefox addon that a developer no longer has up on the addon page

[pcslookout]

I saved it.

How would I go about doing this ?

I have the same issue with Google Toolbar For Firefox .. no longer supported by Google or on the Firefox add on site. Some will say you don't need it, but it has some features I like to use, including some custom buttons (as shortcuts to certain web pages)

You need a developer for this. No other way
