Mozilla will provide security updates for Firefox 115 ESR until at least 115.27.0esr in August 2025
Hi Mozilla Team / Community,
We understand that Firefox 115 ESR will receive security updates until at least version 115.27.0esr in August 2025.
We currently have a number of devices still running Windows 7 for legacy application reasons and rely on Firefox 115 ESR as it's the last version to support that OS.
We need to plan ahead, so could you please confirm:
Will Mozilla continue to support Windows 7 with Firefox 115 ESR updates until August 2025?
Or is support for Windows 7 ending sooner, even if 115 ESR itself continues?

Hi, support for Win 7 will be discontinued when the 115 ESR branch reaches end of life.
After review, it was decided that support for those platforms on the ESR 115 branch will be extended for another 6 months through September 2025 with the final planned release now being version 115.27. We will again review this decision as we approach the new deadline to determine whether further extension is warranted at that time. We have updated https://whattrainisitnow.com to reflect this extension and will be updating other support articles to reference the new date as well. We again recognize that ESR 115 is an increasingly difficult target for patch backports and will continue to limit the scope of approvals to only critical security and quality fixes.
