Yes, of course, and the decisions we've made on porting Tor Browser have
done so.  Even if ugly, our TB needs to be a photocopy of the current
official TB.  But in the future, there are certainly a number of things
we'd push upstream in the interest of portability, in particular.

HTTPS Everywhere is one of the core components of the TB not in
OpenBSD's ports.  But it requires bash, of all things, when it could
easily be done in POSIX shell. That is only one glaring example.

Well, not just portability, considering the long list of bash CVEs over
the years. . .

On that note, if anyone's interested, we're on the third version, 4.5.3,
of the browser.

If you're running a recent amd64 OpenBSD snapshot, definitely give the
install a try.


The README should be clear enough.  Of course jumping into GitHub is
appreciated.  https://torbsd.github.io provides the links to the repos.

We're not there yet, but it's operational and we're getting to a decent
place.  Needless to say, the Tor people say "be wary" if you need strong
anonymity... in our case, wariness should be a state, not a consideration :)
