What does ESR mean in SOFTWARE

Firefox Extended Support Release (ESR) is a version of the Firefox web browser that offers more stability and security than regular releases by receiving only limited updates.

Regular versions of Firefox are updated much more frequently, often on a weekly basis, while ESR versions are updated only periodically, usually every 6 or 12 weeks. This means that users who choose to use an ESR version receive fewer new features but get more stability and enhanced security since the underlying code remains mostly unchanged.

Firefox ESR may be a better option if you're looking for greater stability and enhanced security compared to regular versions of the browser. It may also be beneficial if you want to avoid frequent changes in functionality as new features will generally not be added until the next major release.

Mozilla provides extended support for each major version for at least nine months. After this time, support ends and users are strongly encouraged to upgrade to the latest version.

Yes, organizations such as universities or businesses that rollout large numbers of devices and need stable software with longer term support should consider using Firefox ESR instead of regular versions. Organizations can deploy one version of the software across multiple devices and have confidence knowing it will remain fully compatible with their existing website infrastructure since new features will not be added until after the next major release has been released.
