Mozilla Releases Firefox 17

The Mozilla organization today released version 17.0 of its Firefox browser, for Mac OS X, Windows, and Linux.   The new version incorporates some new capabilities:

  • A revision to the Social API, and support for Facebook Messenger
  • “Click to Play” blocking of outdated or vulnerable browser plugins.  Plugins on the block list will not be loaded unless the user specifically approves them.
  • “Sandbox” attribute implemented for iframes, to improve security

This release also fixes 16 identified security vulnerabilities. Mozilla rates 6 of these as having Critical severity, and 9 as High.  There are also several miscellaneous bug fixes; further details are available in the Release Notes.

Because of the security fixes incorporated in this release, I recommend that you update your systems as soon as you conveniently can.  You can use the update mechanism built into the browser (Help / About Firefox / Check for Updates), or you can get a complete installation package from the Firefox download page.

The “Webmonkey” blog at Wired has an article discussing the new Social API capability in more detail.

Ars Technica also has a review of the new Firefox release.

I should have noted earlier that this release drops support for Mac OS X 10.5 (Leopard).  It is also an Extended Support release, and will receive security updates for 54 weeks.
