Cyberfox is among the latest browser in the wild to make a bold attempt to unseat the likes of Internet Explorer and Chrome. We didn’t mention Firefox, because Cyberfox uses the source code of Firefox.

Using Cyberfox

Cyberfox is powered By Mozilla source code, compiled with Visual Studios and uses Windows SDK.

The ideal users for Cyberfox are folks with 64-bit computers. The designers’ claim the browser is best in such a situation, and from our testing, it is even better than Firefox itself. Not only is it faster, but it uses less RAM, a huge surprise since Cyberfox uses the Firefox source code, and we all know how much of a RAM-hog Firefox has become over the years.

Once the browser is installed and launched for the first time, the option is there to migrate data from Firefox, Chrome, and Internet Explorer to Cyberfox. It works well, so users who are looking to make a full change will have nothing to worry about.

When it comes down to the overall design of the browser, Cyberfox looks the same as Firefox in every way, but what matters most is under the hood and not so much of its looks. However, we suggest replacing the theme because on some webpages, the theme might cause for not being able to see content properly.

Now, things are not all rosy when it comes down to this spectacular browser. There’s a major bug that might not sit well with users, and the team needs to get on it as soon as possible.

As soon as Cyberfox is installed and launched, it takes complete control over Firefox. Should the user close Cyberfox and make an attempt to start Firefox, it will be apparent that Cyberfox will launch instead. The only way to get Firefox back to normal is by uninstalling Cyberfox completely. This is an enormous problem for those who might want to keep and use both browsers.


Cyberfox does what it sets out to do, but not without a few hiccups here and there. It uses less RAM and fewer CPU resources when compared to Firefox, and that is splendid. Just don’t expect to use it on Windows XP, or use it alongside Firefox – not going to work!

Download Cyberfox here. It will work on Windows 7, Windows 8 and Windows 10, but will not work with Windows XP.
