My FF mobile addons: uBlock Origin, I don't care about cookies, ViolentMonkey (it can sync scripts), ClearURLs (with etag and generic filtering disabled!) and Cookiebro.

I really like addons and that's why I don't use chrome on mobile.

Surprisingly I also started using Firefox Focus. At first it looked like nonsense to me, no addons. But then I found out it sometimes makes sense to start from scratch, focus on some topic and delete all tabs with one tap when done. And if I find what I searched for or want to read it later, I share the page to Saved messages on my Telegram. This workflow works surprisingly well for me.

it's the easiest way to get adblock on mobile!
