I tried Waterfox and didnt really get it? Why use it over for example Zen or Librewolf? It just seemed way to close to Firefox but like with a couple of preinstalled extensions. Idk, just wasn't for me.

My browser(s) is just a tool. I use many browsers for different things. I wish there were good alternatives to the main browser engines (Gecko, Blink, WebKit), but I am fine with just using good derivative browsers like Librewolf, Mullvad, Cromite, etc.
