62.0beta Firefox Beta

June 26, 2018

Version 62.0beta, first offered to Beta channel users on June 26, 2018

New

  • Display preview image and favicon in the New Bookmark dialog

  • Added a Clear Site Data and Cookies button to the identity popup located next to the address bar so as to provide a quick and easy process to delete local data for the visited website

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

  • New tab page sections such as top sites, highlights, and Pocket can be adjusted to include 1 to 4 rows in the Preferences

  • Added Canadian English (en-CA) locale

  • Users who disconnect Firefox for desktop from Sync are now offered the option to wipe their personal data from that device (such as bookmarks, passwords, history, cookies, and site data)

  • Added a button to the hamburger menu to toggle Tracking Protection on and off

Changed

  • The description field for bookmarks has been removed. Users who manually changed the field can export old descriptions via html or json. Stored descriptions will be removed in a future release.

  • The release version of Firefox 62 will be sandboxing AutoConfig to the documented API. You can test this in Firefox Beta by setting the preference general.config.sandbox_enabled to true. If you need to continue use more complex AutoConfig scripts, you will need to use Firefox Extended Support Release (ESR).

Developer

Web Platform

  • JavaScript library for interactive editing of CSS Shapes values in the browser, with functional values like polygon(), circle() and ellipse()

  • CSS Variable Fonts (OpenType Font Variations) enable a single font file to behave like multiple fonts
