How do I change the default startup mode to 32-bit mode

This is the message I receive when I try to download my music order from musicnotes.com: Sorry, this plugin requires that your browser run in 32-bit mode. To change the default startup mode of Firefox to 32-bit, click on the screen and select the menu item: "Show me the 'Application Info' window so I can set 32-bit mode myself" I don't know what screen they are referring to. How do I change the default startup mode to 32-bit? Leanne Norman

Thanks to the contributors to Firefox who helped me solve my "32-bit mode" problem. All is well on the Norman computer.

Wait... I have this problem as well but when I open "Get Info" I don't have an open in 32 bit option. Weird. I'm running leopard and Firefox 6.0.2

Do you have a system with a 32 bit processor or are in some 32 bit compatibility mode?

What and where is the "Finder"?

I see, it only applies to an Apple computer, while I have a PC. No wonder I can't find it. Do you have a solution for a PC with Windows 7?

Re: How do I change the default startup mode to 32-bit mode

Official Firefox versions from the Mozilla site that run on a PC are still 32 bit versions and shouldn't require extra measures apart from having 32 versions of all plugins.
On Mac Firefox comes as a i386/x86_64 universal binary and the default is running in 64 bit mode. If you have a plugin on Mac that only has a 32 version then you need to start Firefox on that Mac in 32 bit mode.


Are you running Firefox on a 64 bit version of Windows 7?

Which plugin is causing problems?
