Option-Click AirPort Menu for Network Details

If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.

 
 

Firefox 3.6.4

Send Article to a Friend

[Update: Sorry for the confusion, but the Mac version of Firefox does not have the feature that protects against crashes in plug-ins. -Adam]

Mozilla's Firefox 3.6.4 addresses a handful of security vulnerabilities and improves stability when plug-ins crash. Most notably, if the Flash, QuickTime, or Silverlight plug-ins crash, they won't take down Firefox itself. (Just reload the page to restart the plug-in.) The security vulnerabilities could result in arbitrary code execution, as usual, so it's nice to seem them fixed. Release notes are available. (Free, 17.6 MB)
