c.f. subject, the extension seems to fail in the lastest Mozilla FireFox nightlies. It still works OK in this release:
Mozilla/5.0 (Windows; U; Windows NT 6.1; WOW64; en-US; rv:2.0b2pre) Gecko/20100701 Minefield/4.0b2pre
 
In later releases however, the extension seems to lose all its settings. (It appears to be active but with all the settings gone, it won't show up in the status bar, and obviously all the patterns etc are gone.)
