Change DNS cache timeout on FireFox


Type about:config in the address bar
Filter for DNS


  • network.dnsCacheEntries user set integer 512
  • network.dnsCacheExpiration user set integer 3600

The first entry shows the amount of addresses firefox will keep in cache and not try to resolve everytime.
The second entry is how long each entry will be cached for.

Happy Browsing !!
