Hi.

Please give me some details about your problem so that we could help you.

uninstalled comodo and keep HS, but cannot uninstall HS now.
What do you mean by “uninstalled comodo and keep HS”?

Do you have CIS installed?
What FF version are you using?

Kind regards.
Vadym.

Yes, I installed and uninstalled CIS.
I didn’t select to remove HS during options of uninstall.
FF is 3.5.5
