Waterfox is effectively Firefox's source code compiled for 64-bit versions of Windows.

64-bit is the future of computing – and one obvious benefit of running a 64-bit version of Windows is the fact it allows you to access more than 3.5GB of RAM, helping speed up your computer. Despite the growing popularity of 64-bit though, we're still in that transitional phase where many applications are still only available in 32-bit builds – they're compatible with 64-bit, but you get none of the performance benefits 64-bit computing can bring.

Firefox is one such example: the latest Nightly build is available in 64-bit, but we're at least six months away from it making the transition through Aurora and Beta to a final release.

For those who can’t wait for Firefox to embrace 64-bit, take a look at Waterfox instead. This is a dedicated 64-bit browser based on Firefox’s open source code, compiled specifically for 64-bit versions of Windows, complete with optimizations to help speed things up a little more.

This makes it instantly familiar to existing Firefox users – Waterfox is based on the current stable Firefox build, which means it functions in exactly the same way. Aside from its name on the menu at the top of the main window, there’s nothing to differentiate it from Firefox.

Note, because the app is 64-bit, you’ll need to have installed the 64-bit version of Microsoft's Visual C++ 2010 Redistributable to avoid an MSVCR100.DLL missing error message when you try to launch the app. You’ll also find handy links to 64-bit versions of Flash, Silverlight and Sun Java on the Waterfox download page too, while all add-ons that work in Firefox should work with Waterfox too.

It’s also important to note that Waterfox shares your Firefox settings, so should you come to uninstall it, don’t select the option to delete all personal information if you’re still using Firefox.

What's new in v40.0.2?

- Implemented the patch for Bug 1171966 that fixes slow animations in Firefox since 38
- New logo!
- Fixed an issue that hid the Refresh Waterfox button in about:support
- JavaScript stability should be much better than previous versions as I’ve managed to build properly with the new unified build system.


Waterfox is well worth running if you’re using a 64-bit version of Windows and want to push the performance envelope as far as you can.

Your Comments & Opinion

An unexpected, undesired change

Posted by: Roger, 21 January 2013 17:48

If Waterfox were my main browser, I'd go back to 16. The reason? I don't know if it is Yahoo's doing or Waterfox's or both in cohoots, but Yahoo's home page (logged in) news categories, a key element of their home page, have been rendered effectively unusable with Waterfox 18, vs. Waterfox 16, Opera and IE10. Instead of separate news categories with small sized one-line article leads down the center, easy to peruse at a glance with mouse, the categories are now top tabbed - all or one category at a time - and articles have large 1 to 2 line heads, followed by 1 to 3 lines of text and lots of blank space. Financial quotes have also been moved to the right column, instead of being a single small line under the main news categoy. For me, and I suspect many many others, a large part of the value of Yahoo's home page has been taken away with this layout. Again, I don't know if it's Yahoo's doing or Waterfox's, or some kind of deal between them, but it definitely is not the format I'm seeing with v.16 and those other browsers (Win 7 or 8).

Firefox should have done this long time ago. Its about time there was a x64 version. Needless to say it is better than Firefox with all the addons. Once FF makes the x64 version, then it will be equal. Till then, Waterfox is the way to go. Recommended highly.

Dont forget to have Flash and Java x64 too. reply:

Hi Indy, there is a 64-bit version of Firefox "Nightly" or UX which you can try.

WhatsApp Messenger 2.12.7

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.7 brings:

• Starred Messages
