For you Firefox users:
Mozilla has now released Firefox 13.0.1 for all platforms, which according to the release notes, is designed to not only address the aforementioned Flash issue but also fixes issues with Messenger and Hotmail, and the rendering of Hewbrew text. The update is available for all platforms and should be automatically installed. To force update installation select the “About Firefox” menu item; when the About dialog is displayed, it will check for updates and offer to install if one is available.
WordPress blogs affected by this should upgrade immediately. Yes my blog was affected and the patch fixes the problem. Get it here:
