Mozilla Firefox 22.0 Released with Critical Security Updates

Mozilla sent Firefox Version 22.0 to the release channel. The current update includes fourteen security updates of which four are critical, six high, three moderate and one low.

Note:  According to members at DSLReports, the update appears to have broken the Roboform toolbar.  (H/T, siljaline)

Notable Changes

Social Services:  New to version 22.0 is the ability to disable social media services that may be included with installed add-ons.  To disable social services, open the add-ons manager and select Services to disable or remove any service that you have installed in the browser.

Plain text files:  Word-wrap is a welcome change to viewing plain text files in this version of Firefox.
