Listing your Firefox extensions and their UUIDs

Here’s how to list your Firefox extensions and their UUIDs :

14:11 Marc@Toshiba-Laptop:/cygdrive/c/Documents and Settings/Marc
/Application Data/Mozilla/Firefox/Profiles
/8louy9l2.default/extensions$ grep em:name */install.rdf | 
perl -ne 'if (/({[0-9a-fA-F\-}]+})\/install.rdf:\s*
<em:name>(.*)<\/em:name>/) { printf("%-40s: %s\n", "$2", "$1"); }'

Phew! 🙂
