These are all the browsers I personally think are good and privacy-respecting. Sorry if I accidentally included too many options.
Desktop
Firefox-Based
Firefox
The standard for browsers where you aren’t the product. For maximum privacy it does require tweaking settings, but it is reasonably privacy-friendly out of the box. It has light customization options including a sidebar and customizable button placement, and can be much more heavily customized with user themes.
Librewolf (Most reccomended for privacy)
A custom version of Firefox with enhanced privacy by default. Comes with Ublock Origin installed.
Waterfox
A Firefox-based browser with some additional privacy features, enhanced speed, and additional features.
Floorp
A browser based on Firefox with much more advanced customization options and many additional features, like workspaces and web panels. Doesn’t add any additional privacy-focused features. They recently also added support for chrome extensions. This is my personal choice of browser (with the Natsumi modification).
Zen Browser
A Firefox-based browser with a sidebar+workspace workflow, and lots of stylistic changes and customizations that help put the focus on the webpage. Very nice and usable for productivity, but doesn’t add any additional privacy-focused features.
Chromium-Based
Ungoogled Chromium
It’s Chromium, but without Google. Pretty self-explanatory, it’s simple, and it works.
Vivaldi
An extremely customizable browser packed with a massive quantity of additional features that can be toggled and tweaked for varying needs and methods of usage. It supports MV2 extensions.
Helium
A chromium-based browser with enhanced privacy and speed. Comes with Ublock Origin pre-installed, and supports MV2 extensions. It’s a pretty new project.
Android
Firefox-Based
Firefox
The de-facto privacy-friendly browser, although for maximum privacy it does require tweaking settings. It (and its forks) are the only privacy-friendly browsers on android that support extensions.
Waterfox
A fork of Firefox with more private defaults, and extra bloat removed.
IronFox
A hardened private Firefox fork. Heavily focused on privacy and security, it sacrifices some usability for privacy.
Chromium-based
Cromite (Most reccomended for privacy)
A chromium fork with enhanced privacy and built-in ad blocking.
Vivaldi
Very customizable chromium-based browser. It does not come with an ad-blocker.
iOS
All browsers on iOS are limited to the WebKit engine which Safari is built on, so just use Safari. The benefits of other browsers on iOS are negligible.
