completly different topicif i install a local resolver and start it it caches - so what - the same for nscd which is not default, so you can't blame glibc because caching of an additional package
The *only* reason why Firefox caches Names is because we do not have a local dns caching resolver, so Firefox had to implement its own. If you had a local caching resolver Firefox could be changed to stop caching on its own instead
tell me one reason why *any* application has to cache DNS results at it's own - it don't matter at all if the machine has a local resolver/cache or not, it's not the business of any user application
and just because you have a local resolver firefox won't stop it's behavior
