Hi To update Firefox on Windows 7, you need to be on the Extended Support Release (ESR) channel. Mozilla will provide security updates for Firefox 115 ESR until the end of August 2026. It was previously announced that support would end in February 2026, but in order to ensure our users can continue to browse the web, we will extend support another six months and re-evaluate.
