Vivaldi vs Mozilla Firefox Comments
Top Positive Comment by architsastam · May 4, 2021
Vivaldi is simply the next stop for Firefox users, while it is freeware, it is technically closed and open-source. Some of the browser's components are closed while some are open and the source codes are available on Vivaldi's website.
Top Negative Comment by headlines · Apr 5, 2023
There's no good reason to use a closed source browser like Vivaldi when there are so many open source alternatives on this page.

Chromium vs Mozilla Firefox Comments
Top Positive Comment by John Fastman · Dec 30, 2016
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.
Top Negative Comment by Guest · Jun 5, 2019
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.

Brave vs Mozilla Firefox Comments
Top Positive Comment by John Fastman · Mar 9, 2017
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.
Top Negative Comment by dabockster · Dec 10, 2024
Absolute bait-and-switch of a browser. They advertise privacy and ad blocking, yet you can't disable their crypto wallets or their Web3 stuff. Who knows what else they'll add in future that people won't be able to switch off.

ungoogled-chromium vs Mozilla Firefox Comments
Top Positive Comment by John Fastman · Mar 9, 2017
Despite Chromium being "open source", it still downloads Google-related crap and phones home to Google. If you value your online privacy, you'll appreciate the Ungoogled Chromium browser, which removes all that. However, Firefox remains more customizable in terms of privacy options.
Top Negative Comment by dabockster · Dec 10, 2024
More like GNU/Chromium. It will not load anything deemed "non-free". This includes DRM content, regular Chrome extensions, and a bunch of other random tweaks here and there. Not a good idea to use unless you know what you're doing.
Comment by quifom · Jan 24, 2026
It inherits implements web standards and somewhat better GPU handling from Chromium. Unfortunately cutting dependency on Google comes with it being not very usable. Privacy-wise it's pretty much identical to something like LibreWolf; functionally Ungoogled Chromium is better only for exotic features like Web Bluetooth API.

Tor Browser vs Mozilla Firefox Comments
Top Positive Comment by gunther · Feb 28, 2023
Slower and clunkier than Firefox, but has IP-masking and fingerprint resistance built-in. Definitely the most practical way to browse the web anonymously.
Top Negative Comment by soul1472 · Mar 19, 2026
probably not for usual simple browsing like Firefox, even though Tor is great.
Negative comment by KeenFlosser · Dec 2, 2025
It it not designed to be an alternative. It is for those who need or want anonymity, not for average users' browsing needs.

Top Positive Comment by Thatstinkyguy · Apr 29, 2025
It's Firefox without Mozilla's tomfoolery.
Positive comment by Pablo Almeida · Jul 23, 2026
I Like librewolf because it's simple and reaaly private. Is almost the same firefox, but better!
Positive comment by catnip-teaparty · Jul 8, 2026
LibreWolf has defaults for clearing all browsing history that change the way you store data about yourself, so that it's not really usable as a daily driver web browser, unless you just switch back to Firefox, or you are a person who avoids keeping logs of their browsing history on their own computer.

Top Positive Comment by Akino · Jun 29, 2017
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
Top Negative Comment by Guest · Nov 7, 2019
Dated when compared to actual Firefox, some extensions doesn't work properly due to it being based on a old version of Firefox.

It's a good alternative to Firefox, HOWEVER, it's slop coded just like Firefox. (.claude directory in the browser's code repository)

Comment by dabockster · Dec 10, 2024
It's very promising, but it's currently built almost entirely by college students. Is it going to stay around once they graduate?

Floorp is based on Firefox with support for its extensions, privacy options and Chrome/Vivaldi similar features for customization. Everything without tracking from Google or Mozilla
Positive comment by rabbit-stew · Apr 28, 2025
It's easy to use and customize. It's clean, the preferences are easy to understand. They could do a little better on the support side, but everything else is awesome.
