 No, thanks. With a debug build I get the following assertions:
 {{{
 ###!!! ASSERTION: bad font face url passed to fontloader: 'aFontFaceSrc &&
 !aFontFaceSrc->mIsLocal', file /home/firefox64/TBB/CrashFontDebug/mozilla-
 esr17/layout/style/nsFontFaceLoader.cpp, line 809
 ###!!! ASSERTION: null font uri: 'aFontFaceSrc->mURI', file
 /home/firefox64/TBB/CrashFontDebug/mozilla-
 esr17/layout/style/nsFontFaceLoader.cpp, line 810
 }}}
 This does neither happen with a vanilla Firefox (+ the Tor Browser
 .mozconfig) nor a patched Firefox without the patch 0011. Looking a bit
 deeper then 2a543b9359029938dfa98f8e285fb5528104d527 is still okay but
 b0e19e9a7e94dcbd6e50ea3739c5b3ce218fe57c is not anymore. Thus, this seems
 to be a bug in the fix for #8455 and probably responsible for all the
 crash bugs that showed up recently...
