## Developer comment on this script:
## I would be very happy if this script would not be required.
## Unfortunately, it is required. It works around a lot bugs:
## - There is no deb/rpm/whatever package with Tor Browser.
## https://trac.torproject.org/projects/tor/ticket/5236
## https://trac.torproject.org/projects/tor/ticket/3994
## - There is no way to keep Tor Browser updated.
## (Thandy doesn't exist yet.)
## - There is no way to add the Documentation page well visible to Tor Browser:
## https://trac.torproject.org/projects/tor/ticket/6025
## https://trac.torproject.org/projects/tor/ticket/6053
## - Tor Browsers support for Isolating and Transparent Proxies is very limited:
## https://trac.torproject.org/projects/tor/ticket/5611

Since The Tor Project configured TBB to automatically update itself,
if you would like to keep your browser profile and update rather than re-downloading TBB, you are better off using \
<a href=https://www.whonix.org/wiki/Tor_Browser/Internal_Updater>Tor Browser's internal updater</a>. \
In that case, say no now.<br></br>
