    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

    Dated when compared to actual Firefox, some extensions doesn't work properly due to it being based on a old version of Firefox.

    Largely stays true to the regular Firefox experience. You can still use your Mozilla account to sync, you can still make it look effectively the same, and it seems to nowadays be based on as latest of a Firefox version as possible.

    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.

    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.

    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.

    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.

    Slower and clunkier than Firefox, but has IP-masking and fingerprint resistance built-in. Definitely the most practical way to browse the web anonymously.

    probably not for usual simple browsing like Firefox, even though Tor is great.

    It it not designed to be an alternative. It is for those who need or want anonymity, not for average users' browsing needs.

    I like using opensource and GNU software when I can. I like being able to browse the code, modify things, and install from the source that I audited. Nothing hidden is good.

    GNU anything is usually super restrictive against anything that doesn't fit their definition of "freedom". Avoid.

    It is essentially a fork of Firefox with ONLY private mode. There is no way to sync anything, to install extensions, and generally do anything permanent except saving sites on the home screen for some reason.

    And it has an un-toggleable cookie-banner dismisser, which does not work well, and sometimes breaks sites completely.
