Mozilla Releases Firefox 20

April 2, 2013

Today, the Mozilla organization released a new version, 20.0, of its Firefox browser for Mac OS X, Linux, and Windows.  The new version incorporates bug fixes, performance improvements, and some new features, including

  • Per-window private browsing
  • An improved download facility
  • Ability to close “hanging” plugins without causing other problems

The new release also includes fixes for 11 identified security vulnerabilities, all of which Mozilla rates as Critical.  Further information in available in the Release Notes.

Because of its security content, I recommend that you move to the new version of Firefox as soon as you conveniently can.  You can get the new version via the built-in update mechanism (Help / About Firefox / Check for Updates), or you can get a complete installation package, in one or more of 70+ languages, from the Firefox download page.
