 While testing 4.0-alpha I realized that Tor Browser is not starting
 properly on my machine. Extensions were missing and the following errors
 in the console showed up:
 {{{

 The partition where Tor Browser got extracted had enough space left. The
 only one that was full was /var. Fixing that fixed the start issues as
 well. Not sure what exactly gets written to /var but it seems a disk leak
 to me we need to investigate.
