Log Message:
Update to 62.0

Changelog:
New
    Firefox Home (the default New Tab) now allows users to display up to
      4 rows of top sites, Pocket stories, and highlights

    "Reopen in Container" tab menu option appears for users with Containers
      that lets them choose to reopen a tab in a different container

    In advance of removing all trust for Symantec-issued certificates in
      Firefox 63, a preference was added that allows users to distrust
      certificates issued by Symantec. To use this preference, go to
      about:config in the address bar and set the preference
      "security.pki.distrust_ca_policy" to 2.

    Added FreeBSD support for WebAuthn

    Improved graphics rendering for Windows users without accelerated hardware
      using Parallel-Off-Main-Thread Painting

    Support for CSS Shapes, allowing for richer web page layouts. This goes
      hand in hand with a brand new Shape Path Editor in the CSS inspector.

    CSS Variable Fonts (OpenType Font Variations) support, which makes it
      possible to create beautiful typography with a single font file

    Updates for enterprise environments:
        AutoConfig is sandboxed to the documented API by default. You
        can disable the sandbox by setting the preference
        general.config.sandbox_enabled to false. Our long term plan is to
        remove the ability to turn off the sandboxing. If you need to
        continue to use more complex AutoConfig scripts, you will need to use
        Firefox Extended Support Release (ESR).

    Added Canadian English (en-CA) locale

Changed
    Removed the description field for bookmarks. Users who have stored
      descriptions using the field may wish to export these descriptions
      as html or json files, as they will be removed in a future release.

    Dark theme is automatically enabled in macOS 10.14 dark mode

    Changed the default setting to Enforce (3) for the
      security.pki.name_matching_mode preference

    Adobe Flash applets now run in a more secure mode using process
      sandboxing on macOS. Learn how this may affect features here.

    Users disconnecting from Sync are now offered the option to wipe
      their Firefox profile data (including bookmarks, passwords, history,
      cookies, and site data) from their desktop computer

    Changed how WebRTC handles screen sharing: When screen-sharing a window,
      the window will be brought to front

Developer
    Three-pane Inspector in Developer Tools separates the rules into its own
       panel
