Mozilla Firefox 74 Browser Version released for all platforms including Windows, Linux and Mac and fixes 6 High security Critical Bugs.
Changes in DNS Over HTTPS
When you type a web address or domain name into your address bar (example: www.mozilla.org), your browser sends a request over the Internet to look up the IP address for that website.
Traditionally, this request is sent to servers over a plain text connection. This connection is not encrypted, making it easy for third-parties to see what website you’re about to access.
DNS-over-HTTPS (DoH) works differently. It sends the domain name you typed to a DoH-compatible DNS server using an encrypted HTTPS connection instead of a plain text one. This prevents third-parties from seeing what websites you are trying to access.
The feature is enabled by default for U.S, whereas in other countries need to enable it manually.
How To Enable?
- Just Go to Menu button and select Preferences
- Choose General > Network Settings
- Click Setting > Click on checkbox to Enable DNS Over HTTPS
Another big changes in Firefox 74 browser, it will only support TLS 1.2 or above encrypting HTTPS connections and disabled TLS 1.0 and TLS 1.1.
