Software Update: Mozilla Firefox 31.0

Mozilla has released version 31 of its web browser Firefox. In version 31, Firefox is able to open .ogg media files and PDF documents in Windows, among others. In addition, new tabs get a search field and malware is automatically blocked when it lands in the download folder. Below is the complete overview of the improvements made in version 31:

New

Changed

  • Removal of the CAPS infrastructure for specifying site-specific permissions (via capability.policy.* preferences). Most notably, attempts to use this functionality to grant access to the clipboard will no longer work. The sole exception is the checkloaduri permission, which may still be used as before to allow sites to load file:// URIs.
