A few days ago a new version of Firefox was released. It was advertised as a big change, which makes Firefox so faster they changed the name to “Firefox Quantum”. Is that true? Is the new Firefox all shiny and cool? Maybe. But one big thing that changed is that they moved to WebExtensions API only. It means that now all your addons that weren’t ported to the new format won’t work. Due to that I was very resistant to upgrading to Firefox 57 thinking I’ll stay on 56 for ever.
