Logs and cache of what? The application firewall? > A deactivation of the extension imply the warning "something is not working", surfing is impossible (connection refused). Same goes for manually tweaking the conf. Yes, that's intended. I was just wondering whether the supposed race condition could be avoided that way as Tor Launcher is now out of the picture and the update request should be visible every time it gets issued, in case Firefox is not obeying its proxy settings. You can see those requests in the browser console (Ctrl+Shift+J) after setting the logging pref `extensions.torbutton.loglevel` to `3`). > Would a stack trace be helpful (provided it's gonna happen again)? Could be. I guess ideally having some steps to reproduce your issue would be the best but as long as it seems to be semi-randomly happening (or happened once) that's hard. I wonder if you see those calls with a normal Firefox as well? You could try with setting a proxy (Tor e.g.) and using that for a bit or just using the default Firefox, trying to reproduce those weird `xpcproxy` related firewall alerts. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/25737#comment:11> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
