MUST HAVE

The "MUST HAVE" extensions and addons are those that I would recommend every browser have installed. I would not surf the web without these.

• HTTPS Everywhere
  • Install Links: Chrome, Firefox, Opera
  • "Encrypt the web! HTTPS Everywhere is a Firefox extension to protect your communications by enabling HTTPS encryption automatically on sites that are known to support it, even when you type URLs or follow links that omit the https: prefix."
  • Made by the Electronic Frontier Foundation
  • easy: 5
• uBlock Origin
  • Install Links: Chrome, Firefox, Opera
  • This is by far the best adblocker that exists for either Chrome or Firefox.
  • If you are using this on Chrome, also install: uBlock Origin Extra

Advanced
