Perfect in MacOSX.4, but not in MacOSX.5 Rated 2 out of 5 stars

DownloadStatusBar (DSB) was functioning perfectly in Mac OS X.4 (Firefox 3.5.3), but now in Mac OS X.5 (Firefox 3.5.3, too) it never appears in FF's status bar: The add-on preferences window of DSB is still working, but DSB itself won't show up in FF's status bar.

This review is for a previous version of the add-on (0.9.6.5). 

I haven't had any other reports of problems with Mac OS X.5
