It helps to edit the registry. Delete any default value like:
"%1",,0,0,,,,
in:
HKEY_CURRENT_USER\Software\Classes\http\shell\open\ddeexec
HKEY_CURRENT_USER\Software\Classes\https\shell\open\ddeexec
HKEY_CURRENT_USER\Software\Classes\SeaMonkeyURL\shell\open\ddeexec

Unluckily these values are set again automatically after SM updates or when SM is set as default browser.

For this workaround see https://support.mozilla.org/en-US/questions/791994#answer-153450

As it seems, it is sufficient to clear:
HKEY_CURRENT_USER\Software\Classes\SeaMonkeyURL\shell\open\ddeexec

So we:
1. Should *not* set this key when setting SeaMonkey as the default browser.
2. Should *not* set this key when installing or updating SeaMonkey
