We'll need universal binaries as long as 32-bit-only plugins still exist. To run a 32-bit plugin on a 64-bit machine, we (by default) use IPC. The host process runs in 64-bit mode, while the plugin process runs in 32-bit mode. Or if the user wants to run the plugin in-process (and changes the default settings), Firefox itself needs to run in 32-bit mode.
