If you keep copy of your firefox profiles folder, its not too much work to maintain. Most of the work is an upfront cost of setting up the initial profile.

There is also Librewolf, a Firefox fork which includes uBlock by default and has other security hardened features.

IIRC, DDG is using the system webview for their browser, so the rendering may differ depending on the platform.
