Google announced the new security panel for Chrome from v48 in Chrome’s DevTools, this feature can help users easily know the security information for every network connection/request in a certain website, including the certificate info, now it’s been easier to debug what’s the reason why a website didn’t get a green lock on the url bar(A website using https with enough strengh will have a green lock icon).
For Firefox, open the link below: about:config and click “I’ll be careful, I promise!“, and find network.dnsCacheExpiration, set its value to 0 (create one if it didn’t exist). Now the cache should be flushed, and set network.dnsCacheExpiration back to 3600, or you the cache will not work at all.
Operating system level:
Windows: ipconfig /flushdns
Linux: Depends on the dns service: sudo /etc/init.d/dns-clean restart sudo /etc/init.d/nscd restart sudo /etc/init.d/dnsmasq restart /etc/init.d/named restart

Don’t know what’s the reason why it’ll keep getting deadly segment fault and hang, but it works on my acer Aspire one D150, a super old notebook, the performance is not so good, and I don’t know how to remap the keyboard on it(there are 3 broken keys orz …), so I just quit, ha!
Only 2 screenshots this time … took by my low-end phone.
