Just three days after Mozilla released the final version of Firefox 14 to the general public, the browser maker announced that Firefox 15 is available to download in beta form. With Mozilla's rapid release schedule in place, you won't have to wait long for the new build to go gold. Just over a month, in fact, assuming Firefox 15 is released on August 28, 2012 as currently scheduled. Should you wait for the final build to upgrade?

 

For most people, the answer is yes. A side effect of these rapid fire browser releases is that groundbreaking changes are few and far between. According to the release notes, Firefox brings just three new features to the table for general users, including:

1. Preliminary native PDF support (Aurora/Beta only)
2. Support for SPDY networking protocol v3
3. WebGL enhancements, including compressed textures for better performance

Also included in Firefox 15 is optimized memory usage for add-ons. Beyond that, everything else that's new or changed is aimed at developers, like integrating a JavaScript debugger into developer tools and adding native support for the Opus audio codec. If those don't excite you, neither should Firefox 15.
