Run this on command prompt:
ipconfig /flushdns
net stop dnscache
net start dnscache
after executing first 2 lines , issue in FF resolved and site page loaded accurately.
Hi, Thanks for this tip. This a must for web developers!
You can clear the cache I just did it by Tools > Clear Browsing History.
Untick everything except cache. But I think this will mean websites will re-download stuff again.
Hi,
The about:config fix was so simple, but it doesn’t seem to work. Running 3.6.8 on Linux/x86 (Gentoo) and even after a restart of firefox it’s still caching old entries from /etc/hosts even though I can no longer ping them. Perhaps I did something wrong, although the process was pretty straightforward.
Incidentally, to get out my frustration, I want to say that I hate the fact that firefox caches DNS entries. I don’t think it used to, and now that it does it causes me a headache every day. Why does a browser need to cache DNS anyway? The vast majority of people already have a DNS cache on their computer.
Hey, works great! I managed to flush my DNS cache no problem with this, but do you know how to remove the key after I’ve used it? I’d rather not give it a value so my cache doesn’t flush, but all I could do is reset to string :/
Thanks!
