https://packages.debian.org/sid/firefox Many disagree with this stance, but Testing is in an awkward position and I generally steer people away from using it over Stable or Sid because you get downsides of both without the strengths of either. I blame Debian with shooting themselves in the foot when it comes to communicating this. Testing is not a happy middle-ground, it's a test bed for stable. Staying on Sid gives you essentially a rolling release like Arch and it's plenty "stable" for regular desktop use and should anything break you'll get the fix (usually) faster than on testing.

Sorry for going on a bit of a rant under your post, but I run into this on the regular.

I agree. I chose to focus about stable because that's where Debian "does all the tests" for its packages. I just threw in testing because it happened to have the same version of Firefox, but maybe that muddied the waters a bit.

The fact that the latest Firefox is in rolling release distros/channels but not in stable ones does prove the point a bit; you can either get a new Firefox, or you can get a tested Firefox. I generally prefer rolling releases, but I've had Firefox break in weird ways on Arch from time to time. The only way to get a Firefox that's both well-tested and up to date is to use builds from Mozilla where libraries are bundled, such as with a snap or flatpak.
