Mozilla is rolling out the Firefox 26 update.

One of the most notable changes in this release is an extra layer of security that will prevent plugin content from loading by default. From now on, all plug-ins operate on a "click to play" basis, only Flash is exempt from this rule.
What’s New:
  • NEW: All Java plug-ins are defaulted to 'click to play'
  • NEW: Password manager now supports script-generated password fields
  • NEW: Updates can now be performed by Windows users without write permissions to Firefox install directory (requires Mozilla Maintenance Service)
  • NEW: Support for H.264 on Linux if the appropriate gstreamer plug-ins are installed
  • CHANGED: Support for MP3 decoding on Windows XP, completing MP3 support across Windows OS versions
  • CHANGED: CSP implementation now supports multiple policies, including the case of both an enforced and Report-Only policy, per the spec
  • DEVELOPER: Social API now supports Social Bookmarking for multiple providers through its SocialMarks functionality (see MDN docs)
  • DEVELOPER: Math.ToFloat32 takes a JS value and converts it to a Float32, whenever possible
  • DEVELOPER: There is no longer a prompt when websites use appcache
  • DEVELOPER: Support for the CSS image orientation property
  • DEVELOPER: New App Manager allows you to deploy and debug HTML5 webapps on Firefox OS phones and the Firefox OS Simulator
  • DEVELOPER: IndexedDB can now be used as a "optimistic" storage area so it doesn't require any prompts and data is stored in a pool with LRU eviction policy, in short temporary storage
  • FIXED: When displaying a standalone image, Firefox matches the EXIF orientation information contained within the JPEG image (298619)
  • FIXED: Text Rendering Issues on Windows 7 with Platform Update KB2670838 (MSIE 10 Prerequisite) or on Windows 8.1 (812695)
  • FIXED: Improved page load times due to no longer decoding images that aren't visible (847223)
  • FIXED: AudioToolbox MP3 backend for OSX (914479)
  • FIXED: Various security fixes
