How to tell if you have a 32 or 64 bit browser

 

Internet Explorer

  1. Launch Internet Explorer browser.
  2. Click on the Help tab at the top.
  3. Select About Internet Explorer which will bring up an information window.

If version of IE displays 64-bit Edition, then it is 64-bit IE, otherwise it is a 32-bit browser.

Firefox

To determine whether you are running on a 64-bit version of Firefox, use either of these methods.

  • Check the About Firefox panel
  • Type in the browser address about:support

If you are running 64-bit Firefox, it may be indicated as 64-bit (e.g., Win64); otherwise it is a 32-bit version of Firefox.

Note:

A 64-bit browser (Safari or Firefox, for example) is required to run Java 7 on Mac OS X. 32-bit browsers such as Chrome do not support Java 7 on the Mac platform.
