Secondly it supports old extensions and pocket was removed
Top Negative CommentDated when compared to actual Firefox, some extensions doesn't work properly due to it being based on a old version of Firefox.
Most Recent Commentqasuk834wWhile Firefox is already less secure than Chromium based browsers, they are at least trying. Waterfox is based on a very old version of Firefox without the latest security fixes and tends to be behind for a very long time. Therefore i wouldn't recommend to use Waterfox at all if you want a secure browser.

Brave VS Mozilla Firefox
Comments about Brave as an Alternative to Mozilla Firefox
Comment summary: Brave is praised for its privacy features, speed, built-in ad-blocker, and integration with Tor. However, some users express concerns about its dependency on the Chromium engine and potential tracking issues. Mozilla Firefox, while still appreciated, is seen as less convenient for privacy out-of-the-box compared to Brave. Concerns include recent changes in Firefox and an increase in ads. Brave appeals as a Chromium-based, privacy-conscious alternative, but some users criticize its crypto-focused approach.Top Positive CommentvalerieDespite it being marketed otherwise, Brave DOES track you, and the browser is far too crypto-based for it to be a legitimate alternative for most people. (Did I also mention that there are ads everywhere? First-party ads, not third-party ads, but still.)
Top Negative CommentdabocksterAbsolute 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.
Most Recent Commentavg-gaymerNot only is it not a Gecko-based browser like Firefox, it shoves even more anti-features - primarily ones related to "cryptocurrency" and "AI"- into the users' face by default. Brave's business model is heavily dependent on these unethical services.
176 Chromium alternativesOpen-source browser project offering strong security, fast performance, and stability with broad support for Windows, macOS, Linux, and Android, extensive customization, frequent security updates, minimal default tracking, and foundation for multiple browsers.

Chromium VS Mozilla Firefox
Comments about Chromium as an Alternative to Mozilla Firefox
Comment summary: Many users criticize Chromium for lacking Firefox's features, privacy, and ease of installation on Windows, highlighting its need for user-generated versions and absence of DRM. Despite being open-source, users note privacy concerns as it still communicates with Google. Positive comments mention Chromium as the foundation for browsers like Chrome and Opera, with features like HTML5, CSS3, and addons. However, opinions stress that it requires further implementation for consumer readiness.Top Positive CommentJohn FastmanChromium 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 CommentChromium 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.
