Torifies Midori, Abrowser and Icedove

typo: sniperinfo.net > infosniper.net

Have you considered just routing *you entire traffic* through tor[1]? This should work better, although it might be difficult to set it up to additionally route through a VPN... (but not imposible if you're not afraid of some commands like `ip route')

As to checking the IP address in a terminal - you can check your machine's LAN addresses with something like:
$ ip addr show

There's no direct way to learn the external address, though (the one you have on the outside of the NAT). The best you can do is query a service that reports the address. From console you could do something like:
$ curl https://infosniper.net

Or if you don't want to lose your senses from looking at raw html without syntax highlighting, you could instead do something like:
$ curl https://infosniper.net/ 2>/dev/null | grep -Eo 'the IP [0-9.:]*' | grep -oE '[0-9.:]*'

It's probably not what you wanted, though :/

[1] Note that Debian instructions should to high extent apply to other members of Debian family like Devuan, Ubuntu and Trisquel: https://metager.org/meta/meta.ger3?eingabe=tor+debian+route+all+traffic&submit-query=&focus=web&s=&f=&m=

Just use Tor Browser any time you want to torify.

> Also, what are the inherent risks of Torifying these three particular pieces of software?

No particular risks, but because your browser can be fingerprinted, you aren't really anonymous. So it's self-defeating. The Tor browser will remove the ability to fingerprint and at the same time will anonymize your traffic through the Tor network.

Thank you.
