Excellent! This extension is much needed for Mobile Firefox since it's always harder to manually enter passwords on the phone. Are you planning to do a mobile version? (hopefully that still works in the Maemo build of Firefox which Mozilla abandoned at version 6)This review is for a previous version of the add-on (2.2.5).
SPE depends on an interface (the Saved Passwords window) that does not seem to have any equivalent in Mobile. This will require something entirely different. No guarantees, but I will consider it at least.
EDIT: This is now available as Mobile Saved Password Editor
