What is the difference between Firefox and Firefox Quantum?

  • Hi, I use Firefox, and I know there is this browser called Firefox Quantum. Is it the same like the original Firefox? Or is it a new browser from Mozilla?

  • @davem Yes, Firefox Quantum (aka Firefox 57+) — is it a new browser by Mozilla. It differs in both appearance and funtionality. For example, FFQ does not support full themes, RSS/Atom feeds, podcast and vodcast feeds, JAR archives, XUL/XMPP extensions. But it support all push notifications, hardware media keys (play, pause, stop, fast forward/rewind), extended security settings, more processes.

  • @rexx So, I'll just stick the original Firefox. No Quantum, no problem, Firefox has more features than Quantum.

  • Firefox users who open the About page of the web browser right now will notice that Firefox Quantum is still used as the name of the browser. Starting with Firefox 70, another name is displayed when users open the About page. The new name is Firefox Browser. Firefox users may notice that the logo changed as well.

    It differs in both appearance and funtionality. For example, FFQ does not support full themes, RSS/Atom feeds, podcast and vodcast feeds, JAR archives, XUL/XMPP extensions.

    Hope you got our answer.

  • Thank you for creating this discussion.

    Firefox Quantum is the new, updated version of Firefox.

    Hope this helps!

  • @oliverdavis2006 Hey, but, I heard that Firefox Quantum was named for Firefox version 57, but now, Firefox is in version 86!
