I raise this question because I am worrying about a CA authority WoSign, and now I decide to untrust all SLL certificate signed by WoSign.

Wosign 的 CA有问题，我准备不再信任它签发的证书。


I removed 'Wosign Class 4 EV Server CA G2' from authority list of Firefox, and the next time I review this setting, the authority reappears but all options under this authority (websites, emails , softwares) is unchecked , just as Firefox tech support says.

But when I visit https://www.wosign.com/ , this website still trusted by Firefox. Its certificate is signed by Wosign Class 4 EV Server CA G2, of which I removed the authority.

Can anybody tell me how to make Firefox untrust this CA , and show me alert when I visit any website with SSL certificate signed by Wosign  ? Thank you!

I have to admit I don't really understand how this works. When I remove trust from the root certificate (screen shot #1), then reload the page, instead of not being trusted, there's another authority which is vouching for the untrusted one (screen shot #2). ??!!
