If you'd like to run decent ad blocking extensions (or any extensions) on the Chromium side of things, give Kiwi a shot. Afaik the current Play Store/XDA Labs release is out of date on the security patches' side of things, but the developer is currently working on catching up. Also, the project went open-source not too long ago and apparently the dev's been working together with some devs of a different browser, so you can expect more Chromium browsers to implement support for extensions in the near future. https://kiwibrowser.com

And, well... There's also Yandex with their extension support, they deserve at least a mention. iirc uBO is broken there, but Nano works fine
