Mozilla Firefox 1.5.0.1, and possibly other versions, preserves some records of user activity even after uninstalling, which allows local users who share a Windows profile to view the records after a new installation of Firefox, as reported for the list of Passwords Never Saved web sites. NOTE: The vendor has disputed this issue, stating that "The uninstaller is primarily there to uninstall the application. It is not there to uninstall user data. For the moment I will stick by my module-owner decision.

Security readout for executives and security teams

This issue concerns privacy residue, not system compromise. Firefox 1.5.0.1 reportedly left some user-activity records after uninstall on Windows, so another local user sharing the same Windows profile could see them after reinstall. Mozilla disputed treating this as an uninstaller vulnerability, saying uninstalling the application is separate from deleting user data. Exposure is most plausible on legacy Windows systems where Firefox 1.5.0.1 was used and multiple people share the same Windows profile. Modern managed endpoints are unlikely to be materially exposed unless similar profile-retention procedures exist. Low priority for most organizations unless legacy shared-profile Windows systems exist. The business concern is privacy and data-handling hygiene, not broad compromise. Address through endpoint standards and decommissioning procedures. Mitigation focus: Check Mozilla or vendor guidance before assuming a product fix exists.; Do not share one Windows profile across different users.; Treat browser profile data as separate from application uninstall..
