FAQ
- How do I use the plugin?
-
Go to Settings » DNS Prefetch and enter any domains you want to be prefetched by Firefox browsers, in addition to the ones already linked on your home page. Make sure the “enabled” checkbox is checked.
For example, you might have www.example.com linked on one of your subpages. By adding “//www.example.com” you instruct browsers to resolve the DNS for that domain, decreasing the latency should someone with a Firefox browser visit that page.
