End of the month the browser shows you how it shared that 5 bucks among the sites you visited based on visits, time spent reading, whatever metrics. You can maybe also assing a part of this sum to sites you have a preference of. Let's say you love Momma's baking corner, and allocate 10% more to that site.
This is your payment for the services of the people who create web pages on the Internet. You have no control over that 5 euros, you can only spend it on sites you visited. There you go, everyone pays at least a small sum for what is consumed.
Same approach can be applied to Open Source projects. Since for example Github just doesn't want to implement a proper payment system for the projects they host and exploit.
Problem solved. Companies can have even bigger war chests for this purpose...
As an added plus site owners-creators can show what open source projects they use to run their sites, so those can be also funded with this approach.
