I went to play something on netflix and it said I needed to restart in 32 bit mode, so I clicked restart in 32 bit mode and all it did was exit firefox and reload everything. At that point im guessing its in 32 bit mode now because I can now play movies on netflix. I wanna know how i can test to see if its in 32 bit or 64 bit ; and also how to go back to 64 bit.

There are currently no 64-bit versions of Firefox available, so your system is running the 32-bit version.

Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.

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. Open the Applications folder in Finder
  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
