jsLib-dependent Add-ons

I visited the jsLib clients page here.
http://jslib.moz
dev.org/clients.html

What EXTENSIONS require jsLib in order to work? These are
the only ones 
I know so far.

1. TagZilla
2. Launchy

Can anyone add more to the list?
Are any THEMES dependent on jsLib?
Are any PLUG-INS or SEARCH PLUG-INS dependent on jsLib?
