Restart browser to flush DNS cache.

DNS cache is not stored on disk.

Or type: about:networking (see great answer by Shakiba Moshiri)

You can take look at about:networking#dns which directly lets you clear the cache.

And Where does Firefox keep cached DNS responses? had already been answered by Firefox's Support Team.

ScreenShot: enter image description here

By the way for chrome it is chrome://net-internals/#dns

  1. Open Preferences by typing about:preferences in address bar
  2. Goto Privacy & Security in the menu on the left side
  3. In the History Section click at the link clear your recent history and select:
    • Time range to clear: Today (or whatever fits)
    • Under details select Cache
    • Submit form with Clear now

This worked for me and is the same as the other answer which was down-voted by any reason, maybe people didn't actually try or maybe something else was missing. Not sure if also the DNS cache of the OS needs to be cleared:

  • On macOS I typed in command line: sudo killall -HUP mDNSResponder;say DNS cache has been flushed
  • On Windows it should be Start > Type: cmd > run: ipconfig /flushdns

The new extension framework used by Firefox Quantum doesn't allow functionality like provided by these extensions. That is why they are not being updated to work with Firefox Quantum.

So the way to actually clear the cache is as follows

  • Go to the History menu
  • Select Clear Recent History
  • Check all boxes
  • Under Time range to clear select Everything (except passwords, if desired)
  • Click Clear Now.
