Nouvelle version 52.0 de Firefox



Nouvelle version 52.0 de Firefox.

http://www.mozilla.org/fr/firefox/new/

New
  • Added support for WebAssembly, an emerging standard that brings near-native performance to Web-based games, apps, and software libraries without the use of plugins.

  • Added automatic captive portal detection, for easier access to Wi-Fi hotspots. When accessing the Internet via a captive portal, Firefox will alert users and open the portal login page in a new tab.

  • Added user warnings for non-secure HTTP pages with logins. Firefox now displays a “This connection is not secure” message when users click into the username and password fields on pages that don’t use HTTPS.

  • Implemented the Strict Secure Cookies specification which forbids insecure HTTP sites from setting cookies with the "secure" attribute. In some cases, this will prevent an insecure site from setting a cookie with the same name as an existing "secure" cookie from the same base domain.

  • Enhanced Sync to allow users to send and open tabs from one device to another.

Fixed

  • Various security fixes

  • Improved text input for third-party keyboard layouts on Windows. This will address some keyboard layouts that

    • have chained dead keys
    • input two or more characters with a non-printable key or a dead key sequence
    • input a character even when a dead key sequence failed to compose a character

Changed

  • Removed support for Netscape Plugin API (NPAPI) plugins other than Flash. Silverlight, Java, Acrobat and the like are no longer supported.

  • Removed Battery Status API to reduce fingerprinting of users by trackers

  • Improved experience for downloads:

    • Notification in the toolbar when a download fails
    • Quick access to five most recent downloads rather than three
    • Larger buttons for canceling and restarting downloads
  • Display (but allow users to override) an “Untrusted Connection” error when encountering SHA-1 certificates that chain up to a root certificate included in Mozilla’s CA Certificate Program. (Note: Firefox continues to permit SHA-1 certificates that chain to manually imported root certificates.) Read more about the Mozilla Security Team’s plans to deprecate SHA-1

  • Migrated Firefox users on Windows XP and Windows Vista operating systems to the extended support release (ESR) version of Firefox.

  • When not using Direct2D on Windows, Skia is used for content rendering
