I prefer to use a small netbook over a desktop pc for light web browsing at home. It’s very comfortable but I need something to filter out advertisements.
Squid is rather overkill, so I checked two other solutions: Polipo and Privoxy.
Both of them are easy to configure, offer interesting features (really check it out!), and are constantly updated.
I decided to stay with Privoxy for now because I have more experience with it, but I am inquisitive about Polipo.
