Simply updating the install.rdf file by changing the maxVersion to 4.0.0.* fails for me: FF3 on Win Vista. Absolutely great extension, though.

이 검토는 현재 부가 기능의 이전 (0.9.15.11) 버전에 대한 것입니다. 

that version 4.0.0.* is unacceptable. Try using:
minVersion=2.0
maxVersion=3.0.*

Alternatively... try at the project download page.
