I am trying to determine what Firefox browser version I am running. I typed in about:support to find more info, but I couldn't find clearly where it says what version I'm running. I don't know what link to select to find out, but under "User Agent" it reads: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0
So I didn't know if the WOW64 referred to a 64-bit OS or not?
I would appreciate any help.
Thank you. Katya S.

Your OS is 64 bit, firefox though is a 32 bit application.
Just so you know, you need the 32-bit version of Java to work with 32-bit browsers like Firefox, regardless of the fact that your Windows OS is 64-bit.
