about:config not good enough

NNTP-Posting-Host:  null

I'm trying to delete lines left in the Firefox registry, but About:config
doesn't let me delete them (babylon, funmoods, etc.).

first, where is the registry and wht is it called

second, what do I need in a text editor to properly read, write and save
such file?
