For those of us worried about our browser security, meaning our web browsing being tracked and malicious scripts being executed on our browsers, there are several add-ons to browsers that can help make you more secure and keep your activities private.

• Adblock Plus is a browser security add-on that blocks adverts and popups. It can also stop malvertising infections. Not only that, but it can block advertising and social media trackers.
• Blur has the function to be a password manager and generator. It again helps browser security by blocking trackers and can encrypt data such as passwords.
• Disconnect is another form of tracker blocker. An added advantage of blocking these trackers is websites load faster and consume less bandwidth.
• DuckDuckGo Privacy Essentials is a tool that as opposed to Google, disables search history and blocks hidden third-party trackers. It also tries to increase browser security by ensuring you use HTTPS over an HTTP site. It also rates many site privacy policies from A-F.
• Ghostery is another ad blocker that does its best to stop your activities from being tracked.
• HTTPS Everywhere rewrites all your HTTP requests to websites as HTTPS instead. This ensures greater browser security by ensuring you are using encrypted communication.
• NoScript allows JavaScript, Flash and other executable content to run only from trusted domains you have chosen. This makes many attacks such as Cross-site scripting, cross-site request forgery and clickjacking much harder to execute.
• Privacy Badger is another privacy tool that tries to stop your activities from being tracked.
