Cyberfox Browser Review: Firefox based browser for Windows x64

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.

Cyberfox features at a glance:

  • Ability to close all tabs with a single click
  • The same features as Firefox
  • Enable or disable the new tab page
  • Turn off automatic loading of pictures on the web

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.

    If you want a faster alternative to Firefox, get Pale Moon:
    Pale Moon uses a separate profile, so you can use both Firefox & Pale Moon at the same time.

    Cyberfox is an excellent choice and there’s also a portable version available.

    When is CyberFox going to fix the bug??? I would love to have CyberFox but if I can’t have my trusted FireFox as well then I would have to wait until they fix it.

    If you wish to try many browsers & they all work fine together,i suggest that you use the portable version which are all available.This way you can use them as you wish or simply delete the portable file.
    right now i have 7 differents but my main ones are cyberfox & slimbrowser

  5. Velcro

    Buy the way,you may already know this website but if you don’t & i may suggest it,this is a good place to download free portable softwares.
    You may find most of the browsers & of course leave your comments on their website or i presume here for the readers,

  8. Peter

    I need help about my question.

    Pale Moon uses outdated code and is not very secure.
    Happily using Cyberfox.

  12. bibbinut

    Me too!

    Cyberfox is EXCELLENT.

  14. And Cyberfox is another one of the lame Chrome clone wannabe Fox rebrands. Classic Theme Restorer is a cheap way to “restore” the features to change the UI.

    Australis is a laughable copy of a sane UI! Personally i am more into Vivaldi these days, but i would say for users who want only to customize the UI inside the browser, Pale Moon is enough.

    And as Pale Moon is a real fork, many recent security problems do not appear in Pale Moon as it has none of that Firefox annoyances.

    So, seen from that point of view Pale Moon has less security problems than Firefox.

    Anyway, i just answer this old post because you dear Sir piss me off with your lame attitude! Instead of shit talking and babbling about stuff of which you do not have the tiniest clue you better make yourself useful and try to show the developer the many security holes which you think that they exist.

    If you can not do that, just shut the fuck up! I hate people who bash others projects for no good reason.

    Cyberfox is junk.
    I used to use it but the new ui is terrible.
    They loudly brag on the front page about how easy it is to switch back to the classic UI, but I couldn’t find it anywhere. Clicked on their faq link, it takes me to a useless comment section.

    Just so. Only you can decide, 100 people 100 different opinions

  18. Peter Petropolis

    Because You! could not find it, Junk. Poor boy

  19. Pierre B. Metoyer

    I just tested cyberfox.47.0.2….alongside firefox..46.0.1….They both work.

    You, sir, are the moron. You, sir, are the one who knows nothing! “Celtic God?” Ha! Can you be any more arrogant and egotistical? I think not! However, I can easily see how your neck will snap like a twig one day laboring as it does under the tremendous weight of that enormous head of yours. (No, I don’t mean enormous brain, it would take a microscope to find that. I’m talking about the tremendous heft of all the fat between your ears! Or is it brick? In either case you, sir, are an insufferable bore!)

  21. Strype

    Let me get this straight. You close your post by rudely telling somebody to “shut the eff up,” followed by the fact that you “hate people who bash other people’s projects…” while your opening line does EXACTLY that, by calling Cyberfox a “lame Chrome clone wannabe Fox.” You, sir, are a hypocrite. Not to mention, for many people, Cyberfox is outperforming almost every other browser, including Pale Moon.

    You are certainly entitled to your own opinion, but it would probably be in your best interest to avoid looking like a hypocritical, arrogant schmuck while sharing it.

  22. Strype

    Of course they work. Nobody is arguing whether they work or not. We’re trying to determine how WELL they work. Your post would be a lot more helpful if you were to provide some information regarding how they performed compared to each other. Which one loads faster? Uses less RAM? Has better security measures? Etc…

  23. Strype

    As others have tried to inform you, a browser’s performance is very heavily dependent on your system. There’s only one real method of determining which browser is “best” for you, and that is by simply trying them out yourself, and comparing your results. Good luck!

  24. Strype

    So the program is junk due to your lack of technical ability? That’s some solid logic, my friend. In that case, nuclear power reactors must be giant heaps of metallic garbage, since I have absolutely no idea how to operate one.
