Package request: Tor Browser
“In short, using any browser besides Tor Browser with Tor is a really
bad idea.”
From the very Tor FAQ.

Even though Alpine has the package tor, without the full featured tor-browser, it is insecure for users (who have to use it with other browsers not configured as they should).
