If I install Tor Browser in a custom Whonix-Workstation will it lead to Tor over Tor?

Thanks.

So due to the risks involved I should rather use the real Tor browser. Wouldn’t I then have two Tor connections (Tor over Tor?), and make it twice as slow?

Yes, that would lead to Tor over Tor.

There are advanced users only “experimental” instructions on how to configure Tor Browser with other OS’ to avoid this.

Note: Reading the entire page would be a good idea.

You need to edit /etc/environment/ and add this:
TOR_SKIP_LAUNCH=1

it prevents Tor from being launched when starting Tor Browser
in case of Windows you can create .bat file and put
SET TOR_SKIP_LAUNCH=1
“c:\path\firefox.exe”

change path to where you have your Tor Browser
