Until a year ago, I was using Firefox. I made the switch to Brave, because I wanted the Chromium functionality ( I still think Chromium is designed perfectly to use on mobile. ) but I didn't want any ads ruining it.
But, that might change, I heard about Kiwi here, I'll definitely take a look, extension support with Chromium functionality, that sounds too good to be true. Definitely will try.
Edit: Definitely try it, you will love it. It's not just Chrome with extensions. It also has some features you are missing on mobile, like DevTools. It has Chrome's own 'ad blocker', may not be effective but I downloaded Ublock, which gets the job done. Super, super cool.
