Mozilla has announced a further extension of Firefox support for older Windows operating systems, offering relief to users who rely on Windows 7, Windows 8, and Windows 8.1. Originally, support was expected to conclude in August 2025, but now, Mozilla confirms that it will maintain its commitment until March 24, 2026.
While newer versions of Windows draw much of the development spotlight, a significant user base continues to operate on older systems. For these users, the availability of an updated and secure browser remains crucial. Firefox's Extended Support Release (ESR) plays a vital role here, with the current version, 115, set to transition to version 140 by July 2026.
Commitment to Security
With cybersecurity being a prominent concern, Mozilla has made it clear that security updates will accompany Firefox's extended life on these outdated systems. This decision underscores Mozilla's dedication to maintaining a high level of browser security, even on platforms that many users may have considered obsolete.
Notably, the extension decision will be reviewed next year in February 2026. During this time, Mozilla will determine the feasibility and necessity of continued support. This review will dictate whether users of older Windows systems will retain access to the latest enhancements in browser technology or need to explore other avenues.
- Current ESR: Version 115
- Next ESR version: Set to upgrade to 140 by July 2026
- Support review scheduled: February 2026
This move not only aids users with older machines but reiterates Mozilla's dedication to user accessibility, ensuring that individuals and businesses that have not transitioned to newer systems can still operate securely. As technology evolves, so too does the landscape of user needs, and it seems Mozilla is keenly aware of this dynamic.
For many firms and end-users who continue to depend on older Windows infrastructure for various operational reasons, this announcement provides an additional safety net. Options available under this extended support include performance improvements and bug fixes, albeit within the constraints determined by older Windows architectures.
Ultimately, the decision shines a light on the broader considerations tech companies must balance between innovation and inclusivity, ensuring that no user segment is left behind due to accelerated technological turnover.
