WebEx will only work in 32 bit mode, so I have to make sure Firefox 4.0 is ONLY running this way on macintosh computers. How do I check if this is how it is running, and how to insure it only runs in 32 bit?

Firefox 4 runs in 64-bit mode by default on Mac OS X 10.6 Snow Leopard. You can set Firefox 4 to always run in 32-bit mode in the Firefox.app "Get Info" window, as shown in this screenshot: http://i1209.photobucket.com/albums/cc391/wymette/Firefox4GetInfo.png

  1. From the menu bar, select Firefox and then select Quit Firefox
  2. Open the Applications folder in Finder and locate the Firefox application icon.
  3. Hold down the control key while you click the Firefox icon and select Get Info from the list of menu items.
  4. In the "Firefox Info" window, click the box in front of "Open in 32-bit mode" so that it is checked.
  5. Close the "Firefox Info" window and then restart Firefox 4.
