Disabling the DNS cache of Mozilla Firefox
The DNS cache is used to convert host name to IP addresses in order to fetch requested web page on the internet. Set as defaults, the DNS cache optimizes and improves the performance of request for web page.
Moreover this can be very annoying for webmasters when trying to configure ip addresse manually for a server under test via file hosting.
Below is a tips of how to disable DNS cache set as default for Mozilla Firefox.
First of all, start Firefox.
In the search bar, type
"about:config"
Right click in the list and select
“New” > “
Integer Value”
Enter “
network.dnsCacheEntries” as Preference Name and
“0” as “
Integer value”.
This will disable the DNS cache for Firefox.
