Proximodo acts as a mediator between the browser and the website. It "sees" everything that is going on and, according to your choices, modifies headers and html page content on-the-fly to make things right. You don't want pop-ups and banners? Just activate the corresponding filters and they will disappear. You want cookies to be deleted when you close your browser? Proximodo will do it for you. You want a fast navigation in the pages you already visited? Page caching will be forced.
