Mozilla has released the third (there was no Firefox 3.6.1) update for Firefox 3.6.4 on June 22. This update is the first with the plugin handler (like that of Google Chrome).

Firefox 3.6.4 provides uninterrupted browsing for Windows and Linux users when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.

Users should be prompted soon to update, but can obtain this update via Help the Menu and selecting Check For Updates… For complete list of changes and more information, please see the Firefox 3.6.4 Release Notes.

Next up is Firefox 3.6.6 scheduled for around the end of July. There is not going to be a Firefox 3.6.5 release.
