Firefox: Catppuccin theme with Catppuccin colors applied to the Dark Reader extension

Nope, if your Firefox supports themes then it can support this. You can find the themes here: https://github.com/catppuccin/firefox.

Our goal with the Chromium provided in CalyxOS has been to provide a browser with a solid base of privacy and security enhancements vs Chromium (and by extension, vs Chrome) while still allowing most sites and WebView-based apps to function as expected out of the box. We do this by using select changes from Cromite (and prior to that, Bromite). Some of these include the under-the-hood deactivation of intrusive features and analytics, while others provide additional site settings to adjust features like WebGL and WebRTC, features which are sometimes necessary but which can aid in fingerprinting or identification when turned on. We also bring in the legacy ad blocker from Bromite/Cromite to offer some reasonable protection from the worst kinds of ads. You can find and adjust these features in Settings.

Normally, I'd recommend Bromite as a lightweight Chromium-based browser with built-in adblocking, but the project appears to be asleep right now. It might be worth checking it in a few weeks, though.

Bromite via either its site/Fdroid, GitHub or Woolyss site has a bottom bar available in accessibility settings. (The first one has been unmaintained for a while, but has auto updates available if they ever drop. The other two are up to date but must be updated manually.)

Bromite hasn't been updated since December: https://github.com/bromite/bromite/releases
