Red Hat's major ESR version will be released after the GA period of the first ESR release and before support from Mozilla for the prior release has ended.I'm running Debian 9 and instead of the heavily outdated ESR version of Firefox shipping with this distribution, I would like to always use the most recent Firefox version. Mozilla supports two ESR versions for a period of time when transitioning between major ESR versions.

Mozilla provides Red Hat Development Engineering with the source code and advisories just a few days before they are made public, Once this content is made available, the changes are evaluated, applied, tested, and shipped asynchronously as soon as possible. A 5-work-day deadline is imposed, according to internal SLA for critical CVEs. In general, upstream updates include critical and important CVE fixes.

Update Strategy Minor UpdatesĮSR gets regular upstream security and bug fixing updates every 4 weeks with asynchronous releases for important CVEs. This is also bundled along with the Firefox ESR release for Red Hat Enterprise Linux. NodeJSįirefox requires newer NodeJS as part of the build process. It is currently bundled with Firefox, Thunderbird, and Chromium. GTK 3įirefox requires GTK 3, which is not available in Red Hat Enterprise Linux 6. Similarly, the Rust toolchain from the Developer Toolset program, also available as a module within the AppStream repository, is updated to the latest version when a major ESR rebase is ongoing. As a result, the version of GCC provided by the Developer Toolset program, also known as gcc-toolset within the AppStream repository, is used. Typically on older RHELs the version of GCC required by Firefox is significantly newer than the base distribution. So a rebase of Firefox always requires a rebase of NSS that needs to be done by the Platform Security team. Firefox is currently using the system NSS for security and certification reasons. New Firefox requires a new version of NSS ESR that is typically released upstream roughly 2 months before the Firefox release. Dependenciesįirefox relies on other components that need to be taken into account while preparing a rebase plan.
Red Hat will guarantee that the Web API in a particular major ESR version will be stable and supported, but cannot guarantee that they will be stable across rebased major versions. RHEL API/ABI stability and supportabilityĮven though Mozilla does not provide development packages for Firefox or Thunderbird to link against, they do provide a variety of APIs that are used on the Web. The upstream Firefox ESR release schedule is publicly available on. Development of web technologies is dynamic, the ESR release balances the need to support next-generation as well as much older web applications. Backporting security fixes to older versions within our SLA deadlines is impossible with the resources we have. A web browser is a very security-sensitive component and the volume of CVEs is really high (as many as 17 critical or important CVEs fixed in one update). There are two primary reasons for the Red Hat Enterprise Linux distribution using the upstream ESR release as opposed to the faster-moving Standard Firefox release: That's also a window for us to rebase Firefox in all versions of Red Hat Enterprise Linux.

Mozilla releases updates of the previous ESR for another 3 months to give organizations time to upgrade to the latest ESR. Upstream LifecycleĪ new major version of Firefox ESR is released roughly once a year and gets security/bug fix releases every 4 weeks. This longer-lived release stream is available within the supported Red Hat Enterprise Linux releases. It provides a stable and predictable platform for enterprise web applications. Firefox Extended Support Release (ESR)Ī new version is released once a year, during the year Mozilla provides security and bug fixing releases every 4 weeks. This is the release stream which is available within the Fedora Project. Newer versions are released every 4 weeks, constantly introducing new features, ideal for home users and progressive web applications developers. Mozilla ships Firefox and Thunderbird in two different streams with different use cases. The following overview also applies to Thunderbird. Firefox is the default and only supported web browser in Red Hat Enterprise Linux.
