esr release cycle

About this tag
The ESR release cycle refers to Mozilla's Extended Support Release model for Firefox, which provides a stable, long-term support version for enterprise and legacy environments. Unlike the standard rapid-release cycle, ESR versions receive only security and critical stability backports for an extended period, reducing update frequency and disruption. Recent discussions on WindowsForum highlight Mozilla's extension of Firefox 115 ESR support through March 2026 for older operating systems like Windows 7 and 8.1, as well as macOS 10.12–10.14. The ESR release cycle is distinct from the regular Release channel, which receives feature updates every four weeks. Users managing multiple machines or relying on legacy hardware often prefer ESR for its predictable update cadence and reduced risk of compatibility issues.
