3 with Chrome: Google Dictionary, AdBlock, and StumbleUpon although I haven't used this extension for a long time, I guess I like to stick to well known websites, not for security reasons, lately I find too much diversity unappealing.
Opera - 0, as I use the url filter.ini with Fanboys list there. As Adblock is a memory hog. Chrome - 2, Donottrackme and HTTPS everywhere. Plus a good hosts file.
Using Firefox, I have 7 extensions. 1. Adblock Plus 2. LastPass 3. NoScript 4. Redirect Cleaner 5. Reload Plus 6. Self-Destructing Cookies 7. Smart Referer
With Firefox and Palemoon, I rely upon No Script for security. I used to use a stack but I find they did nothing apart from making browsing more difficult. I would use ABP and a selection of filters but I've got Ad Muncher instead.

Chrome: AdBlock Plus WOT Ghostery Traffic Light Forecastfox Also, in Chrome settings: 1. Block 3rd party cookies 2. "Click to play" for plugins
just one: NoScript. i am very wary about installing any extensions/addons/plugins. if it was included in Firefox i would not be using any addons.
