Firefox version 115 will be the last supported Firefox version for users of Windows 7, Windows 8 and Windows 8.1. If you are using these versions of Windows you will be moved to the Firefox Extended Support Release (ESR) channel by an application update. Mozilla will provide security updates for these users until September 2024. No security updates will be provided after that date.
Microsoft ended official support for Windows 7, 8 and 8.1 in January of 2023. Unsupported operating systems receive no security updates and have known exploits. With no official support from Microsoft, maintaining Firefox for obsolete operating systems becomes costly for Mozilla and dangerous for users.
No. Most browsers, including Google Chrome and Microsoft Edge, have already ended support for Windows 7, 8 and 8.1.
Mozilla is providing critical security updates through the Firefox ESR channel up until the end of ESR version 115, September 2024. After this, no security updates are provided and you are strongly encouraged to move to a supported version of Microsoft Windows.
If you want to keep your Firefox up to date, with all the latest features and updates, you need to upgrade your operating system to Windows 10 or higher. In some cases, Microsoft may require newer hardware in order to support the newer operating system. After upgrading, users can easily reinstall Firefox and keep all of their settings.
