Use Chromium instead of Chrome, it's the open source project that google funds and bases Chrome from, but doesn't connect you to the Google botnet harvesting everything you search/type into URL bar/view whatever.
Chromium has the best TLS stack, and a sandbox. It
would be the most secure browser if it wasn't for Google's awful policy of not checking addons. If you're a criminal you can buy a popular browser addon, reprogram it to steal bitcoins and update through Google's servers and they check nothing. Mozilla does check at least.
http://lifehacker.com/many-browser-extensions-have-become-adware-or-malware-1505117457Essential addons should be Adblock EDGE, which doesn't accept bribes from Google to whitelist ads unlike Adblock Plus.
Disconnect is another good addon, preventing trackers. Connect to any newspaper site, look at the 200+ trackers pile up.
HTTPS Anywhere by EFF is another must have addon.
NoScript is a good idea, and selectively whitelisting sites. Why? Because of all sorts of interesting tab jacking and other shit you can do.
Example:
http://www.azarask.in/blog/post/a-new-type-of-phishing-attack/Go to that page. Then open a new tab. Go to new tab and wait. Surprise! jacked
Pretty good phishing idea, jack the tabs because most people have dozens of them open and won't even notice.
