Need help with putting proxy after Tor (documentation is outdated?)

I’ve read Connecting to Tor before a Proxy and googled for hours, yet I cannot make me → tor → proxy work.
I tried this: user@host:~$ UWT_DEV_PASSTHROUGH=1; TOR_TRANSPROXY=1; torbrowser
and a dozen other variations.

When I check proxy on the host it works well, but in the workstation it doesn’t. Any help?

lammy:

UWT_DEV_PASSTHROUGH=1; TOR_TRANSPROXY=1; torbrowser

This surely is a syntax error.

proof failing:

xxx=a ; env | grep xxx

vs proof working:

xxx=a env | grep xxx

UWT_DEV_PASSTHROUGH=1

Doesn’t hurt, but not required for Tor Browser.

TOR_TRANSPROXY=1

That would only be required for socksifier proxification method. But as
documentation states, there is currently not known to work socksifier
proxyfication method for Tor Browser.

Get a fresh Tor Browser. (Because deactivating effects by
TOR_TRANSPROXY=1 has not been documented.)

Then try proxy settings method as per documentation.

EDIT: Sorry, posted too soon the first time.

Recently tested 3 Methods in documentation:

A. application proxy settings (foxy proxy):
tor browser: working
(using Preferences menu does not work)
iceweasel: working

B. proxifier (proxychains):
tor browser: not working (as stated)
iceweasel: working

C. transparent proxy (redsocks):
tor browser: working
iceweasel: working

This is new info to me. Thanks for updated docs!

@lammy I just added TOR_TRANSPROXY=1 to /etc/environment. Reboot.

EDIT2: /etc/environment method works best when using a dedicated workstation for proxy exits.
If running multiple browsers, either the command line method or editing the startup script is more appropriate.

EDIT3: Gah, since Foxy Proxy doesn’t support chaining of proxies, there’s still no way to exit from a proxy server using Tor Browser with TransPort disabled. Need proxychains to work for that.
