[tbb-dev] Recovering from Broken Tor Browser Nightly

[Matthew Finkel]

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.
