uBlock Origin and Privacy Badger shouldn’t be paired together. Containers do nothing to prevent your fingerprint from being collected. LibreWolf itself is easily fingerprintable. And the user agent isn’t the only telltale sign of your browser and OS, changing it will just make you more unique.

Just use Mullvad Browser with the default settings.

I just can’t give up dwm tbh. dwl is just a mess in terms of using it with a different keyboard layout (the keybinds that come by default work properly only on US keyboards) and needing to use fcitx (fcitx only worked on LibreWolf and nothing else, even after I tried using patches for this).
