Comment (by gk):

 Some first comments:

 It builds and I get proper Tor Browser bundles which is good :). Please
 move `--enable-bundled-fonts` into the respective `.mozconfig` files. It
 is a normal config option which landed on mozilla trunk a while ago. Apart
 from that the tor-browser-bundle changes are good.

 I tested the bundles a bit and was kind of surprised. My naive
 understanding is that tests like they are done on http://ip-check.info
 should show the same amount and the same fonts regardless of the
 underlying OS/testing user or am I missing something here? Anyway, with
 5.0a3 I get 54 fonts on a linux machine and 250 fonts on a windows
 machine. With the patches I get 21 fonts on the same linux machine and 250
 fonts on the same windows machine. While I could understand the former the
 latter sounds like a bug (provided there are no issues with the test
 itself) to me.
