What does it mean that a plug-in can only run in 32-bit mode?

When I go to write a new email this message pops up "This page requires a plug-in that can only run in 32-bit mode" and then I'm asked it I want to restart in 32-bit mode. What does that mean and can I set it up so I don't get this message. It doesn't seem to effect anything if I ignore it.

That means that you have to start Firefox in 32 bit if you want to use that plugin.

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

Had the same problem - couldn't insert attachments to my emails. I have disabled Silverlight Plugin, which solved this problem.

So far, haven't fond anything that would be affected by this.

i didn't have this problem until i updated to firefox 4. and in regard to the above response, yes, you can close down and restart in 32-bit mode, but i would rather it be fixed.
