NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 preserve the network connection used for favicon resource retrieval after the associated browser window is closed, which makes it easier for remote web servers to track users by observing network traffic from multiple IP addresses.
