Hmm, the search function on the forum seems to be working ;)

Yes, but it isn't supported - if you break your system you're on your own.

If its available as a package you can do this.
pkg_add -r frox

Or you can pickup the package with wget.

Some examples using pkg_add here:

In place of using wget, you can use 'fetch' which is on the system by default, and works similarly to wget.
