Mozilla Firefox ESR is an extended support version of the Mozilla Foundation’s Firefox (Web browser). Mozilla Firefox ESR suffers from an information disclosure vulnerability that stems from the fact that in some cases, an asynchronous function may cause a navigation failure that exposes the target URL, which could be exploited by an attacker to obtain sensitive information.
