My shortcut for launching "clean" Chromium session is `chromium --user-data-dir=$(mktemp -d)` -- each launch creates a new transient profile directory under /tmp, which is itself a RAM disk. Persistent settings are achieved by setting system-wide defaults in /etc/chromium, including using system-wide managed policy JSON.
Does this maintain your browser extensions (and their settings)?
Yes, extensions can be installed into the system-wide config via entries in the manged policy JSON. Settings configured in a specific browser session naturally won't persist, though, but defaults set in an initial preferences config will be present.
