Dropbox requires firefox in nixpkgs

[balsoft]

Issue description

Nixpkgs dropbox and dropbox-cli require firefox for installation (and use it as default browser for some reason). I'm using chromium and don't like having firefox in my system. Is there any way to get rid of this useless dependency? I think it should be quite easy to just drop Firefox from buildinputs and don't export BROWSER variable.

Steps to reproduce

nix run nixpkgs.dropbox
