I've discovered recently how to disable most advertisement (including the Google ones) on web pages on Firefox. It works just great. And the manipulation is not that complicated.
I guess this feature will be more and more popular. And commercial or press or any other websites that rely on advertisement will have harder and harder times to get people to see and click on their revenue.
Now OSNews, a free online news site, is proposing you to pay for not having ads, not being annoyed and have the site load faster. All things you can get for free from Adblock in Firefox. I find it ironic the way it's put out : "pay if you don't want us to annoy you".
