[Enigmail] I can't revoke my key

[Stephen Erikson]

Is there another method to revoking a key?  I can possibly check out the
gpg readme there is probably a CLI way to do this but I'm short on time
and just wondered if anyone had an answer to my main problem.

The reason I cannot revoke my key:

I made a key for myself, then tried to remove Enigmail because some
setting got messed up.  When I installed it again I made a new key and
Thunderbird does not see my original key as my own, therefore I cannot
revoke it (I have the revoke cert).

I'm looking for a way to make Thunderbird understand that key is my own.
