I installed CID, because I liked the description of some of the security enhancements. When I installed it, it gave me three choices: use Comodo DNS servers for everything, use them only for IceDragon, or don’t use them at all. I chose to not use them at all, since I use HostsMan with lists like MVPS hosts, so I can whitelist sites as I so desire; and to not allow DNS requests to potentially be logged at a company I do not know much about.
It is installed, and seems to work fine, once I’d chosen a less dark theme. However, when I enter an address that is unknown, such as dfghsdjkfghskldfjghsdifugwernbviurhbvwknb.com, I get page that says Comodo, and that it does not exist, at the DNS.com domain; which is a Comodo domain. I did not expect this to happen, and it suggests that either Comodo DNS servers are being used; or that domain name searches go through Comodo when a domain is not found. I went to about:config, and looked at all the settings that included Comodo, but found none other than for updates and help. Some things that are nonsense that I type into the address bar result in the currently selected search engine called; which is not unreasonable.
I thus request that if Comodo DNS servers, if they are being used, when not selected, will not be used; or that however this Comodo page is being called, you allow for an option for it to be disabled. Even if only a mistyped domain name gets sent to dns.com, it still seems less private to me, than if I used my preferred search engine by using the stock Firefox.
