You don't need anything extra to block internet connections for applications. You can directly block them from the app information itself. I think what you've done so far is very good and sufficient for phone internal use. The important part now is the browser section, and I think you can handle that too.
A test without uBlock Origin would be better.
Go to any youtube subtitle download site
As someone who has installed a lot of roms, I recommend staying with the stock one. It can be really useful on very old phones, but it is not necessary on most current devices. The two biggest issues I had were the lack of floating windows and the play integrity api issue. Also MIUI (without bloatware) is the most useful Android interface. Pure Android is nice and simple but not suitable for everyday use.
I've long stopped using paid wall sites. Still, nice list, thanks.
I don't understand why you're trying to turn this into a ridiculous personal attack. None of the extensions have been tested with the Kiwi browser. Anyhow, enjoy using the extension-compatible Chrome on your phone.
Yes, That makes sense for older phones.
No, the web is terrible without cosmetic filters.
uBlock Origin is only available on Firefox for Android.
Are you talking about the default settings?
Avoid using services that ask for your phone number, for your own good.
Mull is dead on performance and I think you're being very paranoid
