[quote=“adrelanos, post:4, topic:32”]With TBB 3.x you can try to remove the tor-launcher add-on using Tor Browser (same as Firefox’s) add-on manager.
Or try to delete file: tor-browser_en-US/Data/Browser/profile.default/extensions/tor-launcher@torproject.org.xpi
Or set the TOR_SKIP_LAUNCH environment variable to 1. (https://trac.torproject.org/projects/tor/ticket/6009) (I don’t know how to set environment variables in Windows. You might need a small .bat script. Should be easy.)
Then change proxy settings to use socks 5 IP, 192.168.0.10, port 9100 in Tor Browser settings. For the latter,see: https://www.whonix.org/wiki/Tor_Browser#Change.2FRemove_Proxy_Settings
Please try and tell us if it worked.[/quote]
Success! I was able to start the Tor Browser by renaming the file “tor-launcher@torproject.org.xpi”. The Browser starts now and all is fine. Yes, all other applications worked before (normal FF, BTC wallet client…), just the tor browser from the bundle wouldn’t start and issue just an error message (see previous message). As I understand the normal FF with https-everywhere and noscript is still not as hard as the tor browser because it lacks some specific security patches that only the tor browser has. That’s why I asked how to get TBB working on the windows workstation. Thank you again, I am really happy now.
On a side note: After renaming that file, starting the tor browser and applying the socks5 settings as you have suggested, the renamed file has magically disappeared! Only torbutton@torproject.org.xpi is there now. Is this normal? Is TBB doing some checks and deleting files that seem suspicious because they were renamed?
As for the socks5, should I keep the “no proxies for 127.0.0.1”? This was there by default and I kept it.
I haven’t tried removing the tor launcher by going to the add-on manager because the browser wasn’t starting at all so I couldn’t access that manager. Also there is no environmental variable named “TOR_SKIP_LAUNCH” or anything similar in the OS setting. Fortunately renaming that file did the trick.
