The simplest method for finding this information is opening the About Firefox box.

If you don't want Firefox to automatically update right now, you can check whether Firefox is 32-bit or 64-bit on the Troubleshooting Information page. To do this, click the Firefox menu in the upper-right corner of the window and then click the Help icon at the bottom of the menu.
On the Help pane that slides out, click the "Troubleshooting Information" option.
The Troubleshooting Information page displays on a new tab. Look at the "User Agent" section under Application Basics. If it says "WOW64", you're running the 32-bit version of Firefox.
If it says "Win64", you're running the 64-bit version.
If the User Agent section on the Troubleshooting Information page doesn't say either "WOW64" or "Win64", then you're running a 32-bit version of Windows, and you cannot run a 64-bit version of Firefox.
If you use Chrome, you can also check whether you are running a 32-bit or 64-bit version of Chrome.
