I don't recall this ever happening before 3.6.4 and 3.6.5 made no difference. I rarely use a couple of plugins and disabling or deleting them and reinstalling the bundle had no effect on this behavior. Out of a unsubstantiated suspicion I do not use any other connection over such a process until I get Tor Browser Bundle to run properly and verify the connection is correct. Even regular FF configured to use Tor will run fine on top of the tor.process. It recently takes about 5 tries to get it started eventually.Īs advised in this other thread Tor Browser Bundle will run on a completely different disk and away from any system files. I was hoping that there was a bug that would have gotten fixed by 3.6.5 but it wasn't. exe /F will kill all instances of Firefox Aaaaaaaaaanyway. The only way to get it to open is to kill the process and restart. Be careful, because Windows depends on multiple processes/services to run & you. Looking at the process list it says that tor.firefox is running (but it can't be seen). I can run Thunderbird/birdie using the connection and it works fine. The Tor Browser Bundle Firefox will not start up first time. I have noticed ever since 3.6.4 that although the Tor connection is made and can be used by other configured software.

The question Tor Browser Says Firefox is Already Running is very related to this issue but I couldn't add a comment as I am new to this site.
