If ads and trackers are the only things you want to block, you could consider using a PiHole, or even easier, modify the /etc/hosts file to block all the spyware hostnames, and then you can use whatever browser you want.

But the clearnet is so hopelessly broken, there's a massive need to block far more than that, like all the covAIDS propaganda (which will finally be gone soon), 3rd party JS and CSS (just fucking learn how file management works before you code!), custom fonts (browser default is the only font you need!), and other bloat.

And if you go down the /etc/hosts based blocking path, you'll quickly see bars of empty divs everywhere, because soytes reserve that space for ads, which uBlock Origin can remove those divs along with the ads.
Hell, last time I checked Mixi in a WebkitGTK browser, I was shocked by the sheer amounts of ads littered all over the page, it made their propaganda literally unreadable!
At least we have a privacy condom for that now: https://mixi.owacon.moe
And yes, owacon.moe is the new domain specifically for privacy condoms hosted by 076.
