The Slackware Linux Security Team just pushed out fresh Firefox builds for version 15.0 and the current branch because multiple security holes were discovered. These patches tackle four specific vulnerabilities while also smoothing out some general browser performance issues. You can grab the updated i386 or x86_64 files straight from the main FTP servers or any local mirror that carries Slackware distributions. After downloading, just switch to root and run upgradepkg on the package file to finish everything up without much hassle.
