And I wish they did follow semver, but loosely (i.e. major version bump shouldn’t imply breakage, but instead a major new feature). If there is a major new feature, I think they should maintain security updates for the old one for some weeks in case there’s a problem with the new feature.
Firefox doesn’t follow semver so these aren’t major releases. It’s a user-facing app not a library.
