> But distributions often say that it's the only way to keep the whole "ecosystem" of a distribution stable. In practice, it doesn't work. I did a Debian Stretch `apt-get upgrade` and it pulled in a new version of firefox-esr that did not run on my Rockchip Chromebook. Debian was forced to do it because it was end-of-life for the older firefox-esr, and Debian's security backports policy doesn't scale for projects like Chromium and Firefox.
