Check out LibreWolf and see if its defaults come closer to what you want. For me, it's better. I still have to modify a few settings, but not nearly as many as with vanilla Firefox.

that's what I thought. I was against the integration and had to make efforts ever since that inappropriate cash-grab. Glad to see it's dead.

I wish Mozilla would find the funding to stick to being a good browser rather than this current phenomena of waiting to see what the next shitty thing they do to the software is.
