In Firefox 5,while restarting Firefox I have got error message about unresponsive script.I chose to stop it and Firefox opened without pinned tab (normally it opened with the pinned tab),which contained some information on online notepad.Is it possible to restore that information on the pinned tab?Thank you!

Probably not.
You can check the Firefox Profile Folder for the presence of a file sessionstore-##.js with a number in it.


App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data in the file sessionstore.js in the Firefox profile folder.
