Hi Zbynek6, thanks for the reply. I really appreciate it!
For me, the Web Shield doesn't even allow Tor to set up a circuit. The browser never even opens because of this. I've configured it to use a Bridge Relay, and this allows it to connect.
Edit: Well this is interesting. I reinstalled Tor Browser to get you the exact error message, and it works now... Before reporting, I attempted this dozens of times over the course of a few days to make sure the problem was consistent. (To see if it may be Tor node dependent) It failed every time unless I disabled the Web shield. Now I can't get the Web shield to block it...
Thanks!
