I performed a Windows System Restore, from a restore point recorded a week ago. My calendar data added to Sunbird after that restore point was lost. Basically Sunbird user data gets restored along with Windows OS, even though it was my personal schedule (user data). And now I don't know schedule tomorrow!?

Reproducible: Always

Steps to Reproduce:
1. Record a Windows System Restore point (if none exist).
2. Add some new personal tasks and events to Sunbird (add user data).
3. A day later, Perform a Windows System Restore to an earlier point in time.
4. In Sunbird, Notice that the new tasks and events are gone (user data is lost).

Actual Results:  
User data, added to Sunbird after the Windows System Restore point, is lost when a system restore is performed. 

Expected Results:  
User data should remain unchanged in Sunbird after a Windows System Restore is performed.

I have reproduce the steps to get this bug, three times. This bug occurs every time.
