Hmm, i have no possibility to use config dialog, since i use OSX...
When i was playing around with FireGPG, i noticed that under some
undefined circumstances gpg_path resets to default, 'gpg'.
Hope you get this resolved once and for all.

Following worked for me:
conjure about:config
extensions.firegpg.specify_gpg_path true (default false)
extensions.firegpg.gpg_path /usr/local/bin/gpg (your respective gpg location)
Seems that just setting the path doesn't do the trick, specify_gpg_path
must also be set.
Then restart firefox (and verify values in about:config), and you
should be good to go!
