- The 'window.location' object is made a normal overridable object. (MFSA 2010-10)

- Multiple crashes can result in arbitrary code execution. (MFSA 2010-11)

- A cross-site scripting issue when using 'addEventListener' and 'setTimeout' on a wrapped object. (MFSA 2010-12)

- Documents fail to call certain security checks when attempting to preload images. (MFSA 2010-13)

- It is possible to corrupt a user's XUL cache. (MFSA 2010-14)

- Multiple crashes cna result in arbitrary code execution. (MFSA 2010-16)

- An error exists in the way '<option>' elements are inserted into a XUL tree '<optgroup>'. (MFSA 2010-18)

- An error exists in the implementation of the 'windows.navigator.plugins' object. (MFSA 2010-19)

- A browser applet can be used to turn a simple mouse click into a drag-and-drop action, potentially resulting in the unintended loading of resources in a user's browser. (MFSA 2010-20)

- Session renegotiations are not handled properly, which can be exploited to insert arbitrary plaintext by a man-in-the-middle. (MFSA 2010-22)

- When an image points to a resource that redirects to a 'mailto: ' URL, the external mail handler application is launched. (MFSA 2010-23)

- XML documents fail to call certain security checks when loading new content. (MFSA 2010-24)
