Did you get the full installer from; Download Firefox For All languages And Systems {web link}

Please explain the problem in detail. What happens? What are the exact error messages?

I bought a new chromebook and I've been trying to finish the download of firefox and it won't finish. What am I doing wrong?

Firefox is not really made for Chromebooks and ChromeOS in mind.

However you may have a few options depending on the ChromeOS version and kind of CPU you have.

The desktop Linux version of Firefox from Mozilla.org requires a AMD or Intel CPU like you would find in normal desktop or laptops (running Windows, macOS, Linux) that supports SSE2 as ARM CPU's is not supported for Linux from Mozilla, though there may be third-party builds.

Is this an ARM chromebook or an Intel chromebook?
