Sorry to be slightly off-topic, but since you mention NoScript and are familiar with that, this (HTTPSB) and ABP, can I ask. Is HTTPSB more of a NoScript alternative or an ABP alternative?
* Adblock (Plus): Blocking ads, No / minimal user action required
* NoScript: Blocking scripts. Lots and lots of user action required.
* Ghostery: Block privacy intrusions. Basically an application-level firewall for the browser. In a normal firewall, you'd block e.g. port 80 from IP x.x.x.x. In an appliction firewall you simply block, for instance, bittorrent traffic. Minimal user interaction required, and where it is required, it's very easy to use.
* HTTPSB: A low-level web browser firewall ("block port 80 from IP x.x.x.x) that now also does (better) adblocking. The adblocking is on par with Adblock (plus): no user action required. The browser "firewall" is basically unusable. Lots of user interaction required, and when it is required, it's basically impossible to understand.
