Best Android browser hands down, entirely because of the extension support.

I don't know how people use phones with ublock or leechblock. I guess "with less battery life" and "more".

Same experience. For a while I had to do chrome again because it became unusable on my aging phone and then they turned the ship around.

I am always stunned when I have to use anything else at how unusable some pages are without my extensions.

Kiwi Browser for me on Android with full extensions support and developer tools. Any reason to switch to Firefox on Android?

It's extremely outdated now because the developer has abandoned it. I have the vague impression it's lying about the chromium version it's based on as well, or something related to that.

Vanadium for GrapheneOS also supports ad-blocking (enabled by default IIRC).
