Also Kiwi Browser. It's a Chromium fork with extension + adblock support, it even has a developer console.
You must:
1) click kebab menu icon
2) scroll all the way down
3) click ublock icon
4) on another screen click "enter element picker mode"
5) that takes you to the rightmost opened tab (!), so most likely completely different tab than you were using, so you must switch back to your original tab
6) you can finally pick elements
Still, considering that only alternative is Firefox which makes you go to different screen just to switch tab and jump through hoops to be even able to download most extensions, it's still the best Android browser.
