Chromium is an open source web browser that strives for a secure, fast and stable web browsing experience for its users. It is the open source project behind Google Chrome.
As of 2021-01-03 16:59:07, Debian's Chromium package in the repositories for stretch remains vulnerable to numerous CVEs as outlined in the Chromium Security Tracker. Chromium in buster and sid, however, remain up-to-date. Consider using an alternative browser like Firefox if you are on stretch.

You can find these by searching for packages named webext-*.
