Sometimes I get this error:
The session/window data is corrupted:
undefined(undefined)

undefined:undefined

After it happens all subsequent autosaves fail similarly.

[edit] I'm lucky. I just got this error:
This operation failed due to a file access error:
Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIScriptableUnicodeConverter.convertToInputStream](NS_ERROR_OUT_OF_MEMORY)

Unlike the one mentioned before, It doesn't cause errors in subsequent saves.

FF messed up (escaped) some symbols when copying from error boxes.
