[tor-dev] Fwd: Downloadable content: Fonts!

[Nathan Freitas]

Mozilla is adding some new runtime installation features to reduce the
size of the mobile Firefox APK. Is this happening at all on desktop? It
makes me nervous as the "default" config could very much more greatly,
not to mention having a new centralized attack channel.

Good news, everyone!

Our first step to downloadable content has been enabled in Nightly: This
means we now stopped to ship fonts[1] in the APK and instead download
them
at runtime (Bug 1194338 [2]).

With that we reduced the size of the APK by roughly 6.4% (~ 2.7MB) [3].
​
Without having the fonts downloaded (yet) our users can still browse
websites but they may look less nice. And in fact, as things go, a bug
caused just that to happen in Nightly (We don't download any fonts): bug
1249354 [4].
So if websites are currently looking a bit weird on Nightly then that's
because of that. The bug should be resolved soon and after that let me
know
if you see any new weird issues related to (wrong) fonts. :)

Our plans for the future:
* Right now we ship the list of fonts and the location to download with
the
application. We want to synchronize this catalog of content from a Kinto
instance: https://bugzilla.mozilla.org/show_bug.cgi?id=1201059
* We want to download hyphenation dictionaries at runtime too:
https://bugzilla.mozilla.org/show_bug.cgi?id=1095719
* Eventually we might even want to download (some) localization files at
runtime: https://bugzilla.mozilla.org/show_bug.cgi?id=945123

Best,
Sebastian
