Vivaldi

Vivaldi is extremely customizable, presenting a wide range of settings and built-in features designed to put the user in control. Its Chromium-based engine makes it fast and compatible with most Chrome extensions, and Vivaldi removes the code that tracks users from it.
- It's very laggy to open some pages, on Linux, it's hard to install and often lacks basic codecs, so videos on youtube looks pixelated! Guest • Nov 2019 • 13 agrees and 6 disagrees
- The side tab function is very efficient. RemovedUser • Jul 2019 • 9 agrees and 6 disagrees
- As a browser, its efficient, easy to use and customizable. Could still be in beta-phase as there are some bugs and email-client is still missing. Also, no option to have transparent title bar such as Firefox has. twil • Oct 2019 • 2 agrees and 2 disagrees
- Vivaldi is a pretty fast browser, however, it's not a good alternative to Firefox. More than anything Vivaldi is a worse version of Opera Browser. The settings and appearance are good but also limited. 6/10 would recommend. Guest • Jul 2019 • 11 agrees and 16 disagrees
- Vivaldi is like opera minus vpn One thing i dont like is download tab become hard to read download panel Guest • May 2019 • 1 agrees and 5 disagrees
- Vivaldi is fast, has a native note taking service and sidebar. Chrome extensions work flawlessly. Excellent browser. Guest • Jan 2017 • 16 agrees and 10 disagrees
- Vivaldi's user interface offers a multitude of customizations that can only be duplicated on other browsers by installing add-ons. RogueScholar • 13 days ago
- It is very fast and easy to understand savuandreea1 • May 2020
- It's just as customizable (or even more so) but uses Chromium as a base. PaoloGonzalez • Apr 2020
- Vivaldi recaptures what made Firefox and Opera pleasure to use in the 2000s and then some. While modern Firefox and Chrome have been in a race to strip away customization and go for a minimal, one-size-fits-all UI, Vivaldi lets you make your browser look and feel as great as you want. It supports Chrome's vast library of extensions as well. Vivaldi is perfect for the power-user out there. JackVegas • Apr 2020
- Fast. Great tab management. Very customizable. Faster than Firefox. Great history management. Users should give a try. Guest • Jun 2018 • 3 agrees and 6 disagrees
- Dangerous web browser that allows governments to get all your private info and hands it over to them at all times for any reason, no matter how pointless the reason is. Guest • Apr 2018 • 9 agrees and 14 disagrees
- Fast, efficient, and has useful features for productivity. CBagley • Nov 2017 • 4 agrees and 7 disagrees
- Does not contain options to sync browser settings, bookmarks, extensions, passwords, etc. between devices. Guest • Sep 2018 • 5 agrees and 15 disagrees
- Best open source browser that uses the Blink rendering engine possum • Feb 2018 • 0 agrees and 9 disagrees
- Does not adapt aromatically to the high contrast environment (windows - ease of access) thus is impossible for people with vision problems to work with the browser unless someone customize Vivaldi for them. Guest • Aug 2017 • 1 agrees and 6 disagrees
- Vivaldi is clearly inferior to Firefox. Comes nowhere near the same quality Guest • Oct 2017 • 8 agrees and 15 disagrees
- Vivaldi is amazing, it just features everything I like in Firefox, with the speed of the webkit engine ! It accepts chrome extensions. The synchronization support should be added soon. It is better than Chrome for sure. If it was open-source, it would be better than Firefox as well. loxaxs • Apr 2017 • 6 agrees and 10 disagrees
- Fast, customizable, lightweight and is not made by a company that sell ads and spy your online behavior like Google. Guest • Apr 2017 • 1 agrees and 6 disagrees
- Vivaldi cares about users privacy and user experience while on the web. It doesn't have the bloat that comes with Chrome, and the slowness that comes with Firefox. Guest • Dec 2016 • 1 agrees and 13 disagrees

Pale Moon

Pale Moon is an Open Source, Goanna-based web browser available for Microsoft Windows and Linux focusing on efficiency and ease of use.
- When Firefox become more and more bloated Pale Moon is lightweight, offers stability and compatibility with the FF extensions (for now, because WebExtensions). It also works great with a lot of tabs(400 or more). Guest • Mar 2017 • 31 agrees and 12 disagrees
- It has the most similarity to firefox whitout being firefox nightly, which is just firefox but more updated and usually more unstable. It has a mid 2000's site like feel without feeling outdated. It has tons of features, and has some compatibility features with Gecko/Firefox add-ons, which in my opinion makes it a great alternative to firefox. It does not have a blacklist of sites, unlike firefox. Guest • Jan 2020 • 2 agrees and 2 disagrees
- Fast browser. Simple preferences setup. Clean install with no hidden junk in my registry or secret files like chrome and mozilla-firefox. My backup browser is Waterfox. i run on win7 x64. Guest • Aug 2019 • 4 agrees and 1 disagrees
- less bloatware. not control by big company. Guest • May 2019 • 2 agrees and 4 disagrees
- So far, Pale Moon gives me features I want that Firefox has disabled and will soon be gone completely in Firefox 57. Firefox 57 will be a Chrome-like boat anchor. Pale Moon is very stable, lightweight and is fast Guest • Apr 2017 • 22 agrees and 11 disagrees
- Pale Moon is very lightweight (low RAM usage), and maintains the look and feel of earlier versions of Firefox. Essentially, this is the Firefox Mozilla should have made. Guest • May 2017 • 6 agrees and 2 disagrees
- Pale Moon is very good, all sites are loading almost the same as Firefox, but uses less RAM & CPU, so the system is working faster than with Firefox, and also removed unnecessary functions. Pale Moon add-ons are very useful, especially YouTube Downloader and Adblock Latitude. Configurable very, very nice browser, 10 out of 10 points. Guest • May 2018 • 0 agrees and 1 disagrees
- It is faithful to the core principles of Firefox (customization, extendibility, user friendliness...), avoiding the bloating and the questionable decisions taken in the last years by Mozilla. Pale Moon is the browser for those of us that loved Firefox in its golden years. Guest • Jun 2018 • 1 agrees and 2 disagrees
- Pale Moon resembles old Firefox, and maintains support for old extensions, and old features. Guest • Mar 2018 • 2 agrees and 1 disagrees
- Firefox classic UI and faster than Firefox. It's more user friendly and easier to use. Firefox is too jumbled and complicated. Guest • Apr 2018 • 0 agrees and 2 disagrees
- Firefox is no longer just a good browser. Firefox is going to be a Google Chrome clone. It is dropping support for legacy add-ons. Firefox is dropping support for XP and Vista. Pale Moon has committed to retaining support for add-ons, menu's, security and still remains lightweight. Guest • Apr 2017 • 7 agrees and 4 disagrees
- It's way faster than Mozilla Firefox Guest • Jun 2017 • 0 agrees and 2 disagrees
- Much more stable than the actual firefox. 1 crash per day vs. 1 crash per two weeks on MacOSX Guest • Mar 2016 • 15 agrees and 10 disagrees

Brave

Brave Web Browser is a fast, free, secure web browser with a built-in ad blocker*, tracking and security protection, and optimized data and battery experience. *What is Brave Ad Replacement? Brave’s goal is to speed up the web, stop bad ads and pay publishers. One of the ways we plan to accomplish this is with ad replacements. We will also invite users to fund their wallets and to use those funds to pay the publishers of their favorite websites.
- Not secure at all, based on Chromium as 99% of the browsers. It doesn't get my respect. No differencial, just Chromium + some extensions implemented. Guest • Nov 2019 • 14 agrees and 6 disagrees
- JohnFastman made a review 2 years ago when Brave was using Muon Browser as a source. Brave now officially supports Chromium extensions because it uses Chromium as a source, so feel free to use Brave as a replacement for Google Chrome and Firefox. Guest • May 2019 • 4 agrees and 8 disagrees
- Brave is open-source and privacy focused like Firefox. It uses the open Chromium Engine used also by Chrome and so it is really fast. It has built-in Tor and a good Ad-blocker. Brave intrduced a new way to reward content publishers with privacy-minded ads (you can activate/deactivate this feature when you want). Guest • Jun 2019 • 2 agrees and 4 disagrees
- I have been using FireFox for years. Recently I have been inundated ads. I noticed that after a recent FireFox update, none of the plugins were operating. I was unable to install updates to the plugins. I decided the try Brave. Elminated all ads, and I didn't need a plugin. Also it is much faster than my FireFox. Guest • May 2019 • 4 agrees and 8 disagrees
- Its super fast, private and has Tor implemented. Its reliable and ive never had any problems with it, The_Quantum_Alpha • Mar 2019
- Feature of different user profiles and earning money from ads - those two I only found at Brave. c4rismoore • 4 days ago
- Currently (March 2017), Brave is not a mature project. It's an open-source privacy-oriented browser and very fast. But you rely on the developers to provide most of the privacy settings, and you can't install extensions. Firefox remains much more customizable via it's about:config menu options. JohnFastman • Mar 2017 • 15 agrees and 8 disagrees
- It's really really nice and fast, but is still in very early development and lacking a lot of features Guest • Apr 2017 • 9 agrees and 4 disagrees
- Built-in ad-blocker, free and open-source. Guest • Feb 2018 • 2 agrees and 3 disagrees

Waterfox

Waterfox is a high performance browser based on the Mozilla platform. Made specifically for 64-Bit systems, Waterfox has one thing in mind: speed. What makes Waterfox so fast? It's built with Intel's C++ compiler. One of the most powerful compilers out there. This enables us to make the fastest possible web browser for all the code changes we make. This potent combination makes for an unparalleled browsing experience.
- Fast, supports the old extensions. Guest • May 2019 • 10 agrees and 2 disagrees
- Waterfox is made for x64 (amd64) CPUs, and it also delivers you a fine service concerning privacy, firstly devs removed telemetry and tracking implented recently in Firefox. Secondly it supports old extensions and pocket was removed Akino • Jun 2017 • 31 agrees and 10 disagrees
- clean striped open-source alternative if you seek a browser without any telemetry features Schnatt_App • Feb 2020 • 3 agrees and 1 disagrees
- Fast. Support for XUL addons. Interface customisation unrestricted x Guest • Aug 2019 • 4 agrees and 2 disagrees
- Please keep it updated quicker vs Firefox. That is my only complaint. Guest • Dec 2019
- The 64 bit version of this browser is very lightweight. In fact, it can compare with 32 bit version of another browser. khanhlong17112000 • Oct 2019
- It depends what you want from a Firefox alternative. Waterfox is essentially identical to Firefox, except that it's a 64-bit, not a 32-bit browser. It's still open source and fully compatible with all options, extensions and everything else. JohnFastman • Dec 2016 • 20 agrees and 7 disagrees
- Dated when compared to actual Firefox, some extensions doesn't work properly due to it being based on a old version of Firefox. Guest • Nov 2019 • 1 agrees and 0 disagrees
- Great 64-bit alternative, it's lighting-fast & ditches the telemetry. Guest • Aug 2017 • 9 agrees and 4 disagrees
- It is completely compatible with every feature present in Firefox, so you don't lose *anything* when migrating, and win privacy, speed and security. Guest • Oct 2017 • 6 agrees and 4 disagrees
- Uses almost all the original code of firefox but keeps the "undesired" NPAPI that firefox dropped, another words user retains ability to change the browser's UI & behaviour Guest • Nov 2017 • 3 agrees and 1 disagrees
- Open source fork of Firefox with a few privacy settings (not not all) changed by default. Guest • May 2018 • 1 agrees and 0 disagrees
- So far this is the BEST replacement I have found for FireFox 57 (which is just a Chrome clone at this point) Guest • Nov 2017 • 2 agrees and 1 disagrees
- Waterfox is so far the closest to modern Firefox, but with better privacy, and a commitment to maintain XUL/XPCOM support indefinitely so that I can keep using a modern theme with square tabs, centred bookmarks and of course the add-on bar. bird • Nov 2017 • 3 agrees and 1 disagrees

Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web. An unofficial portable version of Chromium is available here: http://crportable.sourceforge.net Windows binaries are available at: https://chromium.woolyss.com
- Chromium doesn't have DRM features and some codecs implemented like Google Chrome, it's open-source but all your data goes to Google when you use Chrome Store to download apps since there is no Chromium store. Also, this browser is hard to install on Windows, you have to compile or download versions that are created by the users daily, so it means you do not have a proper installer like on Linux/BSD. Guest • Jun 2019 • 12 agrees and 5 disagrees
- Chromium is the core of the Chrome browser. It functions well enough as a browser but lacks some of Chrome's features (e.g. built in language translator). Even though Chromium is open source, it still "phones home" to Google, which has privacy implications. There are more private Chromium-based browsers, such as Brave and Iridium. JohnFastman • Dec 2016 • 40 agrees and 15 disagrees
- Chromium is most likely the heart of Google Chrome, Opera and some browsers without fancy features. SiliconeValley • Sep 2016 • 15 agrees and 11 disagrees
- Chromium is not a ready-for-the-consumer software. It is a open source project that needs to be implemented to make it work. jacksarrocco • Jul 2016 • 27 agrees and 106 disagrees

Google Chrome

A free web browser developed by Google from the open source Chromium project with a focus on speed and minimalism. Chrome offers fast start-up and web page loading, supports a minimalist user interface, automatically updates in the background, and offers syncing of browser bookmarks, extensions, passwords, and history between multiple computers by your Google account.
- It doesn't have the same level of privacy and personalization Guest • Mar 2017 • 155 agrees and 17 disagrees
- Bad add-on/script compatibility, less freedom for modding the browser Guest • Aug 2015 • 128 agrees and 30 disagrees
- Do not have as many languages and spell checking support as Firefox do. Guest • Dec 2016 • 83 agrees and 19 disagrees
- Not open-source, which is the major reason for using Firefox. Guest • Jan 2018 • 32 agrees and 5 disagrees
- The purpose of Mozilla is to offer a free, open source browser that protect privacy while Google chrome purpose is to exploit private data to promote Google Ads. Guest • Feb 2018 • 23 agrees and 4 disagrees
- Less customization with add-ons, closed-source code and Google privacy issues. Chrome is what Firefox is trying to be with FF 57 / WebExtensions, but it won't work, just like how corporate Democrats will never be able to win enough Republican voters over to replace their progressive base. Stop trying to be Chrome, Mozilla. Guest • Nov 2017 • 19 agrees and 7 disagrees

- chrome is cool but is not best alternative for firefox voreni • Jan 2020 • 0 agrees and 2 disagrees
- Completely different way of addons, different way of process handling, independent from Goole, more intuitive to handle, perfect for power users, completely different way to secure addons (provides much less working surface for malware). Guest • Oct 2017 • 16 agrees and 5 disagrees
- Google Chrome is the fastest and most secure browser there is. It also has the largest library of extensions and the most support since it is by far the most widely used browser today. shadomatrix • Jan 2019 • 3 agrees and 9 disagrees
