The Mozilla Foundation releases an important security update for Firefox. All users should upgrade to the latest version (0.10.1) of the Firefox Preview Release. A patch is available for current Preview Release users.

Download information:

• Visit the Firefox homepage to download the latest version of Firefox Preview Release (Firefox 0.10.1)
• Current Firefox Preview Release users: when the update icon () appears in the upper right corner of your screen, just click on it to install the patch, or click here to install it.
• If you already have Firefox 0.10 installed, you can also go to Tools, Options, and choose Advanced, go to Software Updates and choose Check Now

This fix came after it was discovered that a malicious hacker who could trick a user into saving a file could delete files from a user’s download directory.
