12 Browser Plugins That Enhance Your Privacy And Security


NOSCRIPT
“Allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks, “Spectre”, “Meltdown” and other JavaScript exploits.”
This plugin disables scripts by default, and lets you choose which ones to activate. This feature is crucial for browsing the web securely. Webpages with javascript are like computer programs– opening random webpages with javascript is almost like installing random software without an antivirus.

This is an alternative to NoScript that is also available for Chrome.

UMATRIX
This is like a hardcore version of NoScript. By default it blocks all sorts of content, and only allows what you enable. You can choose the exact types of content to block and the exact web addresses, all displayed on a handy grid. Highly customizable.

MULTI-ACCOUNT CONTAINERS
“Firefox Multi-Account Containers lets you keep parts of your online life separated into color-coded tabs that preserve your privacy. Cookies are separated by container, allowing you to use the web with multiple identities or accounts simultaneously.”

DECREASE PRODUCTIVITY
This plugin helps you browse anonymously in the physical proximity of other people. It will dim images and make every webpage look the same, so you can read anything while at work, until your boss finds out you have this plugin. It’s also useful if you find the diverse images and colors around the internet annoying.
