Installing HTTPS Everywhere Mozilla Firefox add-on increases your Internet web surfing security by always using secure communications, if available, between your web browser and the website you are visiting.
Many websites offer both the insecure way (HTTP) and secure way (HTTPS) to access them, but only advertise the insecure way (HTTP). This is often because they don't know how to configure and manage web sites and focus only on the website content without paying attention to their visitors' security.
When you visit such a website, Firefox will connect to the insecure version (HTTP) because that is the version the website is advertising. To connect to the secure version (HTTPS) of the website, you would
have to change the URL (website link) in the Firefox address bar from http://somewebsite to https://somewebsite.
This is no way to surf! Luckily, there is a better way.
With the HTTPS Everywhere add-on (extension) installed, you will always be connecting to the secure version (HTTPS) of the website you are visiting. It automatically detects if the website offers a secure version (HTTPS) and instructs Firefox to use it.
By installing HTTPS Everywhere you will always know that your web communications are as secure as possible, because Firefox will always use the secure version (HTTPS) of the website if it is available.
HTTPS Everywhere was created by The Tor Project and the Electronic Frontier Foundation, two incredible projects that make the online world a much better (and much more secure) place.
