I'm running FF 3.6.4 with Windows Vista Home Premium. When prompted to download FF 3.6.6 I did, but when I restart FF it refuses to install FF 3.6.6, saying it cannot until I quit FF. But this happens even when I restart Windows, i.e. when FF is definitely not running.

This happened

Every time Firefox opened

== I downloaded FF 3.6.6 from within FF 3.6.4, using check for updates.
