This depends on the level of paranoia and your own involvement in controlling what third parties may know about you. That said, heres a starter list.

RequestPolicy & NoScript -- both extensions are superb for privacy and security because they operate on a whitelist premise: nothing is allowed unless you personally review it and allow it. Its also the biggest drawback from my opinion: controlling them and setting them up correctly takes weeks.

LastPass -- this extension is a locker for all your passwords. Its very secure and generates passwords that are strong. Its portable and very useful.

Great question. Ghostery is a type of extension that carries a database with itself (that is updated daily) and using this database, Ghostery compares traffic requests going out from your browser to see if they are a known app (this is called black-listing btw). On top of that, if you happen to set up your Ghostery to block some or all applications through Ghostery options or the panel, then Ghostery will also prevent some of those requests from ever occurring. When Ghostery blocks something, the purple alert box will have the name of the application crossed out to let you know that Ghostery has blocked it on this page.

Next major version of Ghostery for Firefox (v3) is implemented using the new addon SDK (jetpack). This makes it portable to Firefox Mobile and its currently on track for release in the next month or so. If you really want to get before everyone else, contact us through our support board (getsatisfaction.com/ghostery/) and I'll send you a copy.

The OS initiative has been taking a while for us simply because Ghostery, while looking the same for all releases is not in fact the same codebase.

That said, our code isn't obfuscated or hidden in any way, so if you're interested in taking a look under the hood, feel free to download whichever version you're interested in, renaming it to .zip and extracting the contents, and cracking it open with your favorite editor.

Ahh, well, you are looking at Ghostery options page. Now, if you take a closer look, you will see the "Select All" button. If you press it, all the apps will be selected to be blocked, don't forget to press "Save". Also, you can click on each category name and it will expand to show you the entire list. You will also see checkbox next to each name, thats the toggle that signifies if you want to keep this company blocked or not.
