Title: Firefox 140 Arrives With ESR Status

Link: https://news.slashdot.org/story/25/06/24/2210...

Longtime Slashdot reader williamyf writes: Firefox 140 just landed. Some user-
facing features include: Vertical Tabs: You can now keep more -- or fewer --
pinned tabs in view for quicker access to important windows. Just drag the
divider to resize your pinned tabs section. Unload Tabs: You can now unload
tabs by right-clicking on a tab (or multiple selected tabs) and selecting
"Unload Tab." This can speed up performance by reducing Firefox's memory and
CPU usage. But the most important feature? This release is an Extended
Support Release (ESR). Why are ESRs so important? ESR is the Firefox version
that ships as the default with many Linux distributions. Some downstream
projects (like Waterfox) depend on the ESR version. Many enterprise software
systems are tested only against ESR. When features are dropped -- like
support for older operating systems or Flash -- ESR keeps that functionality
around for longer. And speaking of old operating systems: If you are using
Windows 7, 8.1, or macOS 10.12~10.15, note that FireFox ESR 115 (the last
version supporting these OSs) will continue to receive patches until at least
September 2025. So one can see why ESR is very important for some people. The
release notes are available here.
