This does not mean that support for Windows 7-8.1 and macOS 10.12-10.14 will be discontinued immediately, but Firefox used on these operating systems will automatically transition to the Firefox Extended Support version, which has a slower update frequency.

Mozilla said in a blog post on the 6th that ``Firefox is the only major browser that still supports users of these operating systems. Users who migrate to Firefox ESR 115 will receive security updates until at least September 2024.'' He announced that the update provided for the old OS will end in September 2024 at the earliest.

Regarding the reason for the end of support, Mozilla said, ``Microsoft ended support for Windows 7 to 8.1 in January 2023.With no official support from Microsoft, it is for Mozilla to maintain Firefox support for older OSs. It's costly and dangerous for users.'

Most Chromium-based browsers such as Google Chrome, Microsoft Edge, and Vivaldi will drop support for Windows 7-8.1 in February 2023. As a result, Firefox was the last major browser to support operating systems prior to Windows 10.

Mozilla plans to continue security updates for Windows 7 to 8.1 until September 2024, which means that ``after September 2024, there will be virtually no browsers that can browse the Internet on these operating systems''. I'm here. Also, in October 2025, about a year after that, Microsoft will end support for Windows 10, so browsers will follow suit and stop supporting Windows 10 sequentially.

Mozilla strongly recommends upgrading the Windows version, especially for corporations, because updates are not delivered to older OSes and may pose a security risk. We need to consider September 2024 as the end of support for Windows 7-8.1 and macOS 10.12-10.14.'
