Firefox on android can just install extensions. No clue about the iphone. I remember some chromium browsers also having extensions on Android but I’m not 100% sure which ones.
There’s also DNS blocking of ads which can be set in your DNS settings or be part of your VPN connection. This will effectively block all ads too (even embedded ones in apps). On android ofc, yet again no clue about apple.
