Firefox ESR v115.x Support for Win 7 and 8.1 Extended to March 2025

Further to my (now archived) 09-Jul-2024 topic Firefox Support for Win 7 and 8.1 Extended Beyond September 2024, the official Firefox release calendar at https://whattrainisitnow.com/calendar/ now shows that support for Firefox ESR v115.x has been extended to March 2025.

Once Firefox ESR v115.21 is released on 04-Mar-2025 Mozilla will decide if a further extension is required. See Martin Brinkmann’s 09-Aug-2024 ghacks.net article Mozilla extends Firefox 115 support for old Windows and macOS devices for more information.

The 19-Feb-2025 ghacks.net article Mozilla Extends Firefox Support for Windows 7 to September 2025 notes that Firefox ESR support has been extended once again for Win 7 and Win 8.x users. From the official Firefox ESR release schedule at https://whattrainisitnow.com/release/?version=esr:

We decided to extend support for ESR 115 only on Windows 7-8.1 and macOS 10.12-10.14 up to September 2025. We will re-evaluate this decision in August 2025 and announce any updates on ESR 115’s end-of-life then.
