Description TEJ RATHI 2026-11-03 08:29:35 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Epiphany's incognito mode uses the global dconf setting for auto-open-schemes, which stores the domain of a visited site when the user clicks the "Always Allow" option. This undermines one of the purposes of incognito mode by persisting the visited domain in Epiphany's configuration.
