| You sometimes can, though you've got to know what to ask for, and what you're trading off. FWIW, this is what platforms such as Debian attempt to provide. It's a challenge, and something of a losing battle, especially with complex and fast-moving tools, notably Web browsers, but also development toolkits (scripting languages, Web development environments, etc.).
Debian stable attempts to provide a stable feature set + bugfixes for all packages. Increasingly, even on Stable, there is the option to install packages which continue to offer feature updates, including for web browsers. Though there is also the option of an LTS or ESR package install. These are specified versions with extended bugfix / security support, typically called Long Term Support (LTS) or Extended Service Release (ESR) version of a package. You'll find these with the Linux Kernel, for example. And yes, Mozilla has an ESR programme which "receives major updates on average every 42 weeks with minor updates such as crash fixes, security fixes and policy updates as needed, but at least every four weeks." https://www.mozilla.org/en-US/firefox/enterprise/ Firefox ESR is currently at release 78.10.1: https://www.mozilla.org/en-US/firefox/78.10.1/releasenotes/ I believe that's based on 78.0.1, first released in June, 2020:
