Hello everyone, Today you may discover that Tor Browser Nightly does not bootstrap tor and only shows the red error page. This is due to on-going work improving the initial bootstrapping experience [0]. Unfortunately, only part of the changes were merged yesterday, and that resulted in the current broken state [1]. As described in [1], the workaround is setting the `TOR_USE_LEGACY_LAUNCHER` environment variable as `1`: `export TOR_USE_LEGACY_LAUNCHER=1` or `TOR_USE_LEGACY_LAUNCHER=1 ./tor-browser_$l/Browser/start-tor-browser` Sorry for the inconvenience. This issue should be resolved tomorrow. [0] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/27476 [1] https://gitlab.torproject.org/tpo/applications/tor-launcher/-/issues/40009
