Mozilla Extends Support for Firefox on Older Operating Systems
Background
Firefox, the renowned web browser developed by Mozilla, had announced plans to cease support for its Extended Support Release (ESR) version 115 on older Windows and macOS operating systems in September 2023. However, a substantial number of Firefox users still rely on these legacy systems, prompting Mozilla to reconsider its decision.
Extended Security Updates
In a surprising turn of events, Mozilla has declared that it will continue providing security updates for Firefox 115 ESR on Windows 7, 8, and 8.1, as well as macOS versions 10.12 through 10.14. This extension will grant users an additional six months of support, until September 2025.
Rationale for Extension
Mozilla’s decision to extend support stems from its recognition that many users may not have the necessary resources or capabilities to upgrade to newer operating systems. By continuing to provide security updates, Mozilla aims to ensure the protection of these users’ online activities and data.
Review and Future Plans
Mozilla has stated that it will reassess the situation in August 2025 and determine the future end-of-life date for Firefox ESR 115. This decision will be based on the number of users still utilizing the older operating systems.
Focus on Modern Systems
While Mozilla recognizes the need to support legacy systems, it actively encourages users to transition to more up-to-date and supported operating systems, such as Windows 10 or 11, and macOS 11 or 12. These newer systems offer enhanced security features, better performance, and compatibility with modern applications.
Firefox 135 Update
In addition to extending support for Firefox ESR 115, Mozilla has also released Firefox 135 as the latest stable version of the browser. Firefox 135 includes several bug fixes and performance improvements, addressing issues in dropdown menus, history, search, and other areas.
New Anti-Tracking Feature
Firefox 135 also introduces a new anti-tracking feature called Bounce Tracking Protection. This feature blocks websites from using "bounce tracking" techniques, which can compromise user privacy by following the user’s activity across multiple sites.
Cross-Device Tab Accessibility
Another notable addition in Firefox 135 is the ability to view open tabs on other devices. Through the Overview section, users can now access a list of tabs open on their other synced devices, allowing for seamless continuation of browsing sessions across multiple platforms.
Conclusion
Mozilla’s decision to extend support for Firefox ESR 115 on older operating systems is a welcome move that prioritizes the security of users still relying on these systems. However, it is important to note that Mozilla encourages users to upgrade to newer and more secure operating systems as soon as possible. With the latest Firefox 135 release, users also benefit from enhanced anti-tracking protection and cross-device tab accessibility, further safeguarding their online privacy and improving their browsing experience.
