    This is the real deal. You get all the features you'd expect from Firefox, but Mozilla's anti-features are disabled by default. Additionally it offers more privacy features Mozilla doesn't want you to have.

    For more convince you may want to undo some of the privacy tweaks, but it's not a dealbreaker and having strict defaults is good.

    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.

    Cons:

    • as base is used a very old version of Firefox
    • bad user experience (interface)
    • an very old (and probably already unsupported) version of Sync
    • no support for modern plugins, extensions and themes

    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.
