One of the major security incidents that web browser users may face is the fact that an extension has ceased to be maintained. From the reason that, Google introduced in version 117 Chrome (and we assume Chromium as well) mechanism to notify when an extension has been removed from the Chrome Web Store.
The user notification feature for extensions removed from the Chrome Web Store was explained by Oliver Dunk via the Chrome Developer Blog. The developer said the mechanism would be triggered if the extension was removed by its developer, was removed by Google for violating store policies, or was flagged as malware.
Dunk explains that they designed this feature to keep the Chrome ecosystem safe for users while reducing the likelihood that genuine extensions will be broken by Google’s policies. If the problematic extension is fixed, the warning will automatically be removed. However, the user will not be notified if the developer is notified of a potential violation and given a period of time to fix the issue or problem.
You can review notifications about extensions that have been removed from the Chrome Web Store in the Security Checkup section of the Privacy & Security section. located on the left side of Google Chrome Settings. From there, the user can choose to view extensions that aren’t in the official store and decide what to do with them one by one, whether to hide the notification or proceed to remove them. Giant Mountain View reminds that extensions marked as malware are automatically disabled.
Google cares about the security of its users (privacy protection is another matter), so the removal notice from the Chrome Web Store is not the only improvement it is preparing in this regard. In addition to the above, Google reminded about this started implementing automatic update of all URLs in Chrome 115 http://
on https://
in order to enforce the use of a secure version of the protocol and the traffic encryption it provides. This “ensures that Chrome only uses insecure HTTP if HTTPS is not actually available.”

Another security improvement that will be introduced in Google Chrome is this the user will be warned when they try to download a potentially very insecure file over an insecure connection. The company warns that downloaded files may contain malicious code that bypasses the isolation provided by the browser and other protections present on the computer, thus opening the door for an attacker to compromise the computer.
Every added level of security, however small, is appreciated. On the other hand, Google can’t make the excuse here that it’s a giant corporation with tons of resources, so it has more than enough resources to design and implement security measures in both Chromium and Chromium.
