 We might need a fixup patch for our OCSP and Favicon isolation in ESR45.
 If one takes `https://dist.torproject.org` as an example URL I can see
 things like
 {{{

 [01-01 00:00:00] Torbutton INFO: tor SOCKS:

 and
 {{{

 in the log output. Note the differing `nofirstpartyhost-chrome-
 browser.xul` and `Nofirstpartyhost-chrome-browser.xul`.
