Yes, as long as you are using the same type of system as your own.

Hi, I've wanted to download Firefox on a Chromebook using a flash drive. Is it possible? Thanks.

There is no version of Firefox for the Chrome OS however there may be a few options to try depending on what hardware you have. Android Firefox and Linux Firefox may be possible.

You can download whatever version of Firefox you want regardless of what OS your are using.
