I use it on mobile just for uBlock. As far as I know it's the only mobile browser that supports extensions. If you use their nightly version it can use any extension that you can get on desktop. The base version only supports a few extension, but uBlock is one of them.
I'm progressive on economic policy, and libertarian on social values. I support things like universal healthcare and ubi. I also support decriminalizing all drugs and legal prostitution.
