rolfe@ - can you confirm those strings in the mocks are the final ones that passed strings review? :
- Browser
- Downloads
- Incognito
- Media
- Sites (until split out in https://bugs.chromium.org/p/chromium/issues/detail?id=700377)

Also what was the final string for 'Content suggestions'?
(cc sfiera@ who may end up implementing this one)

Confirming all strings! Also "Content suggestions" was the final one for that one too.

Removing myself and adding chowse@ as your trusty design contact

Resolving this bug as fixed - content suggestions are not broken out yet but leaving that to sfiera@ to land when appropriate.
