On the Java download page for Mac OS X, it says:

Chrome does not support Java 7. Java 7 runs only on 64-bit browsers and Chrome is a 32-bit browser.

If you download Java 7, you will not be able to run Java content in Chrome and will need to use a 64-bit browser (such as Safari or Firefox) to run Java content within a browser. Additionally, installing Java 7 will disable the ability to use Apple Java 6 on your system.

I understand the above and want to download Java 7 for Mac OS X (10.7.3 and above).

Since when is Firefox a 64-bit browser?

There are 64-bit versions of Firefox they are just not being maintained by Mozilla at this current time ( their focus moved away from this for some reason ). Furthermore the statement is not a percise statement notice that use of such as they were only examples. In reality your only other choice likely is Safari. Of course Chromnium can also be compile to be a 64-bit browser. – Ramhound Aug 13 '13 at 19:21
Apple is unique in that it does not all 32-bit software on a 64-bit operating system to a certain degree it seems. Furthermore the last statement is just funny, of course installing Version 7 of the Java SDK should disable Version 6 of the SDK. – Ramhound Aug 13 '13 at 19:24
@Ramhound: that is the Windows's 64 bit version of Firefox be abandoned, not Linux and Mac. Currently all Mac apps are 64 bit. You can have a look at firefox repository – Lưu Vĩnh Phúc Aug 30 '13 at 9:09
I said as much minus the typo in my second comment – Ramhound Aug 30 '13 at 10:06

Firefox for OS X indeed is 64-bit. From the build info:

clang -arch x86_64

Go to about:buildconfig to check it:

This has been the case since version 4.0, according to a mozillaZine mod.
