Browserslist: Unknown version 73 of firefox

[equinusocio]

Some recent Browserslist updates broke my postcss build process (using parcel and postcss-preset-env). The Firefox query return an error about missing version 73.

  "browserslist": [
    "last 1 Chrome versions",
    "last 1 Firefox versions", <--- broken
    "last 1 Safari versions",
    "last 1 Edge versions"
  ]

Using npx

➜ npx browserslist "last 1 Chrome versions, last 1 Firefox versions, last 1 Safari versions, last 1 Edge versions"
chrome 80
edge 76
firefox 73
safari TP

Seems like https://github.com/browserslist/browserslist/pull/438 fixes it too (thanks for the issue anyway, the question was why do you have unknown browser, seems like Babel uses as in wrong way)

Fixed at 4.8.5
