Mozilla has extended support for Firefox 115 ESR on unsupported versions of Windows, including Windows 7, 8, and 8.1, until March 2025. Initially set to end support in September 2024, Mozilla reassessed the situation due to the continued presence of users on Windows 7 and decided to extend support for an additional six months. Mozilla plans to reassess its support strategy in August of this year. Meanwhile, the latest versions of Firefox, including version 135 on the Release Channel and version 128 on the Extended Support Release Channel, are available for users on newer operating systems.
