The Firefox Public Data Report also reveals that Windows 7 still provides a sizable portion of the overall Firefox userbase (13.44%), while Windows 10 is the leading platform with 71% of users. During its one-year support cycle, each Firefox ESR version only gets incremental updates containing security fixes with no new features or performance enhancements.Īs stated by Firefox's official release calendar, Firefox 115 ESR should come out on July 4, 2023. Firefox ESR is stable release of the open-source browser which Mozilla supports for an extended period of time compared to regular, 'rapid' releases coming out every month. Mike Kaply also hinted at the fact that Mozilla still has to decide exactly when support for Windows 7/8 will be finally removed. Mozilla programmer Mike Kaply confirmed the decision through the Bugzilla platform, stating that the corporation 'will not be ending support for Windows 7/Windows 8 before the release of the Firefox 115 ESR,' and that the Firefox 115 ESR release will support the aged operating systems 'at least until 3Q 2024.' The Extended Support Release (ESR) of Firefox will keep supporting Windows 7 and Windows 8.1 until at least until 2024. Mozilla won't be among such companies, however, as the open-source foundation has decided to postpone the fateful date for quite a while.

Why it matters: Windows 7 went out of Microsoft's extended support (through the Extended Security Updates paid program) in January, and software companies are now revealing they will do the same in the upcoming months.
