Comodo Dragon is a Chromium-based web browser with additional controls for DNS filtering, referrer handling, sign-in, and private-session behavior. It opens ordinary websites and compatible Chromium extensions, so its daily workflow resembles other browsers built on the same engine. Comodo Dragon changes several privacy defaults, but it does not make a session anonymous or replace endpoint protection. Websites, Internet providers, extensions, and signed-in services can still observe parts of the browsing activity.
Choose the DNS scope
The installer can leave the current DNS provider in place, use Comodo Secure DNS for Dragon only, or apply it to all applications on the computer. The browser-only choice changes name resolution for browsing without redirecting every other program. The system-wide choice also affects mail clients, games, update tools, and any application that asks Windows to resolve a domain.
This difference can change access to internal company names, parental filters, or local network devices. Record the previous DNS settings before choosing the all-application option. If another program stops reaching a service after installation, test the original provider rather than assuming the remote service failed.
Import with intent
Comodo Dragon can import selected records from the default browser during setup. Bookmarks are usually straightforward, while history and saved settings may carry old sites or behavior into the new profile. Import only the categories that serve the migration and inspect saved credentials through the browser’s password controls afterward.
A copied bookmark does not move an active login session. Sites can still request authentication because cookies, device checks, or account tokens did not transfer in the same way. Keep the old browser until important accounts have been tested, then remove its stored data through that browser rather than deleting random profile files.
Privacy switches differ
Referrer suppression limits the address information sent when following a link. This can reduce one form of navigation tracking, but some sign-in, payment, or download flows use referrer checks as part of their logic. If a trusted site loops or rejects a transition, test its flow with that setting off before disabling other protections.
Starting in incognito mode reduces local history and closes temporary cookies with the private window. It does not hide the public IP address, encrypt traffic beyond the site’s connection, or stop a signed-in account from recording activity. A Do Not Track request is also a request; each site decides how it responds.
Extensions keep permissions
Comodo Dragon supports compatible Chromium extensions can come from the Chrome Web Store. Each extension runs with the permissions accepted at installation, and those permissions may include reading page content or changing visited sites. Comodo Dragon’s DNS filtering cannot make a broadly privileged extension harmless.
Review extensions after a browser update and remove ones that no longer have a clear job. A web-store listing can remain visible even when an older browser engine cannot run the latest release. When an extension fails, compare its required Chromium level before reinstalling it repeatedly.
Updates define exposure
A browser engine parses untrusted web content every day, so its security state depends on timely engine updates. Additional privacy switches do not compensate for missing Chromium fixes. Check the browser’s update status and compare its engine generation when a site reports unsupported capabilities.
Use Secure DNS as one filtering layer, verify certificate warnings instead of bypassing them, and keep a separate backup of bookmarks. If a current web service requires engine capabilities that the installed Dragon build lacks, moving that service to a maintained browser is safer than forcing the page through an obsolete rendering path.
