The following instructions will show you how to setup SSH key based authentication, using Ubuntu 12.04, on a local and remote machines.
I originally discovered Adblock Plus when I first downloaded Firefox many years ago. Since then I’ve installed the Adblock plugin right after Firefox, etc. It’s become so standard that I almost think Firefox should just bundle them together. Including it in it’s default install exe.
Adblock Plus works as if it were a local content policy, filtering each request you make with Firefox. Each URL, each domain, each link you navigate to is check based on a static blacklist of expressions and URLs. If a match is found, Adblock Plus simply discards the content from rendering. The discarding and allowing content to load is managed by the Content Policy engine within Firefox. Adblock Plus simply utilizes this in order to block the unwanted contents. Or at least this is my comprehension of how it works. :-p
