Simple: I don't believe you. Grab this copy of Firefox from 2022, https://www.firefox.com/en-US/firefox/96.0/releasenotes/, and run it on a modern distribution in 2026. If you fail, my point is made.

Does Debian Stable count?

And yes, it runs perfectly fine on Debian 13.

I dunno about firefox (newer crypto libs wont work) but I ran a gimp compiled in 2018 on a 2025 distro.

Why specifically FF? Software without TLS does run just fine 5 years later on 5 year newer distros.
