When I press Reply to a message in Hotmail, a yellow bar appears saying I need to restart with a 32-bit plug in. I tried this, but the problem still occurs.

That is a problem with Silverlight

On a Mac, Firefox 4 is a 64 bit application.
Not all plugins support 64 bit and if not then you need to start Firefox in 32 bit mode to use that plugin.

  1. Close Firefox
  2. Start the Finder and open the Applications folder
  3. Right click or control-click the Firefox.app icon
  4. Select "Get Info"
  5. Select or Deselect "Open in 32-bit mode"
  6. Close the "Firefox Info" window
  7. Restart Firefox

It appears there is an update to Silverlight for the Mac which works with 64-bit Firefox. I got the warning from Netflix after upgrading from FF 3.6.18 to 4.0.1 and immediately to 5.0 yesterday. Used Firefox's built-in plugin update checker (under Tools > Add-Ons) and got the latest Silverlight from Microsoft, shut down Firefox 5 and installed it. Now it works fine and Firefox is in 64-bit mode.
