The latest Mac-only update to Mozilla’s open-source Web browser, Firefox 5.0.1, brings only two changes, but they’re important. First is a workaround for a crash that could occur in the forthcoming Mac OS X Lion when using downloadable fonts. Since downloadable fonts are quite common on the Web, Firefox 5.0 users would have seen significant numbers of crashes after upgrading to Lion. Second, Apple’s update to Java in Mac OS X 10.5 Leopard broke the Java plug-in in Firefox (see “Java for Mac OS X 10.6 Update 5 / Java for Mac OS X 10.5 Update 10,” 29 June 2011); version 5.0.1 enables Firefox to load the Java plug-in in Leopard once again.

View Extra Audio Details in Snow Leopard
In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
