Is Firefox 5 beta 2 32-bit only?

Question

Is Firefox 5 beta 2 32-bit only? I can't seem to find an x64 download.

Answer 1

You can get the latest Firefox (Nightly) from their server.

The file is called firefox-7.0a1.en-US.win64-x86_64.installer.exe

You can find full Firefox files here

For Firefox 5, Beta 2, I only see one version available from here.

Beta 3 is not available for Windows as of yet.

I do recommend the nightly build if you want to be on the bleeding-edge. You get the latest features and tests before anyone else, and it will automatically update at start if there are changes. Remember though, there are some bugs you may come across using it (since Nightly is their testing stuff), so if you do find bugs, report them to the developers!

Created most weekdays from the previous day's work, these builds may or may not work. Use them to verify that a bug you're tracking has been fixed.

We make nightly builds for testing only. We write code and post the results right away so people like you can join our testing process and report bugs. You will find bugs, and lots of them. Mozilla might crash on startup. It might delete all your files and cause your computer to burst into flames. Don't bother downloading nightly builds if you're unwilling to put up with problems.

Now since you asked the difference between 32 and 64 bit versions, here's a little information from Microsoft:

The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.

With a 32bit version of Firefox though, you should not see any issues since it does not access huge amounts of information at a time from the RAM.
