Comment (by boklm):

 On some systems, this can cause an error like this when starting the
 browser:
 {{{
 /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.23' not
 found (required by $FOO/tor-browser_en-US_8.09a/Browser/libxul.so)
 }}}

 A temporary workaround is to edit the file `Browser/firefox` to move or
 copy the line `add_LD_LIBRARY_PATH "$basedir/TorBrowser/Tor/libstdc++/"`
 outside the `if`:
 {{{
 diff --git a/projects/firefox/start-firefox b/projects/firefox/start-
 firefox

  add_LD_LIBRARY_PATH "$basedir/TorBrowser/Tor/"
  export LD_LIBRARY_PATH
