Comment (by sysrqb):

 Great, thanks! I think the most noticeable change resulting from this
 patch is that favicons are not downloaded.

 The patch prevents connections for the following functionality:
  - Sending Crash reports (already disabled) - `CrashReporter.java`
  - Search suggestions (SuggestClient.java)
  - Pocket (already broken, needs API key) - `PocketStoriesLoader.java`
  - After installation from Google Play (under certain conditions) -
 `Distribution.java`
  - Downloadable Content (Disabled at compile time) - `dlc/BaseAction.java`
  - Top/Suggested Sites - `ImageLoader.java`
  - (Fav)Icon download per tab - `IconDownloader.java`
  - Region-specific search engine (always default in TBA because missing
 API key) - `SearchEngineManager.java`
  - Download A/B testing framework config (already disabled) -
 `Switchboard.java`

 As a result, the newly broken functionality includes Image downloading for
 Top/Suggested sites and favicon download.
