Description

Last year
The default "network.dnsCacheEntries" pref is set to 400. This has been the Firefox DNS cache size default since November 2008 (bug 453403).

The web and Firefox have since changed a lot and we're using and resolving way more names now.

Let's double the cache size and monitor closely how this affects the cache hit rate.

(The independent DNS cache eviction enhancement in bug 1463374 should also make Firefox use the existing cache better.)
