For example: 1. Certificate "CA.A" is trusted by firefox by default. 2. Certificate "CA.B" is issued by certificate "CA.A", but not stored in firefox by default. 3. Website "WWW.C" use a certificate "CA.C" which is issued by certificate "CA.B" 4. After I visit "WWW.C", firefox will report it is a secure connection and will add "CA.B" to "Certificate Manager".

Now I want to untrust "CA.B" and all certificate issued by it.

In firefox old release(like firefox 45), there is an "Import" option in "Certificate Manager"->"Servers", I can import "CA.B" to untrust the certificate. In firefox new release(like firefox 112), there is no "Import" option in "Certificate Manager"->"Servers", so I can not untrust "CA.B". I have also try to untrust the certificate in "Certificate Manager"->"Authorities"-"Edit Trust", but uncheck the checkbox can't untrust the certificate and firefox still report it is a secure connection when I visit "WWW.C".

I'm currently running V. 89 on a Windows-7 machine. The system runs a GE-Force 700 series video card. I just recently added more RAM to my system (currently 4 GB) and the OS is running all the latest W-7 updates. I want to upgrade to the latest FireFox version (112), but am having problems with it. When I go to run V. 112 on YouTube, there is an annoying hesitation whenever a video is running and I go to move the mouse around the page with the video stopping for 1/4 second and then restarting with each mouse movement. I disabled hardware acceleration, but the problem still won't go away. I don't see it on other sites, just YouTube. It's so annoying that I uninstalled V. 112 and re-installed V. 89. Any suggestions? Thanks.
