I need a little help, if you would, please...

So I've been using DDG on my phone for a while now, but it seems to be rapidly enshitifying. The only thing I like about it at this point, is that it blocks app trackers. The browser and search suuuuuuuck, so I've got Firefox back on it with uBlock Origin. So my questions are these two: What can I use to block app tracking like DDG does, so I can get rid of DDG? And is the ClearURLs addon for FF good/safe/does what it's supposed to? If not, what is?
