Firefox 116 drops support for Windows 7 and 8, as well as macOS 10.1 ↺
Earlier today, Mozilla released Firefox 116.0 for Windows, Linux, and macOS users on desktop systems. While Android users also received this update today, mobile users on iOS were still stuck with version 115.0 at the time of publishing. While being just a security update, Firefox 116.0 also includes a few noticeable changes and marks the end of support for a few Windows and macOS versions.
Those still using macOS 10.12, 10.13, and 10.14 will continue to receive support via Firefox ESR alongside Windows 7, 8, and 8.1 users. While they will not get Firefox 116.0, they can already upgrade to Firefox 115.1 ESR, which also arrived today. Other changes included in Firefox 116 include enhanced HTTP/2 upload performance, the introduction of a volume slider in Picture-in-Picture mode, as well as various security fixes, as usual. More information about these security fixes can be found on this page and it should be highlighted that this update addresses no less than 7 issues considered to have a high-security impact.
In addition to all the above, Firefox 116.0 comes with a new approach to handle Ctrl+Shift+T, which now reopens the last closed tab or window by default. When there are no windows or tabs to reopen, the previous session is restored by this command. According to Mozilla, "This change is in anticipation of upcoming changes to recently closed tabs."
The update can be applied automatically or manually across all available platforms, as usual.
