 {{{
 Tor Browser Bundle (2.3.25-7); suite=windows

 {{{
 * Firefox patch changes:
      - Apply font limits to @font-face local() fonts and disable fallback
        rendering for @font-face. (closes: #8455)
      - Use Optimistic Data SOCKS handshake (improves page load
 performance).
        (closes: #3875)
      - Honor the Windows theme for inverse text colors (without leaking
 those
        colors to content). (closes: #7920)
      - Increase pipeline randomization and try harder to batch pipelined
        requests together. (closes: #8470)
      - Fix an image cache isolation domain key misusage. May fix several
 image
        cache related crash bugs with New Identity, exit, and certain
 websites.
        (closes: #8628)
