Many new features & security updates & --> ending support for many older OS

Version 115.0, first offered to Release channel users on July 4, 2023
In January 2023, Microsoft ended support for Windows 7 and Windows 8. As a consequence, this is the last version of Firefox that users on those operating systems will receive. Users on Windows 7 and Windows 8 will automatically be migrated to the ESR 115 version of Firefox so that they continue to receive important security updates. Visit
this Firefox support article for more information.
Similarly, this is the last major version of Firefox that will support Apple macOS 10.12, 10.13, and 10.14. Users on those operating systems will be migrated to the ESR 115 version of Firefox so that they continue to receive important updates. Visit

We want to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!
