That can be caused by clearing the cookies via "Clear Recent History".

- Firefox/Tools > Options > Privacy > Firefox will: "Use custom settings for history" > [X] Clear history when Firefox closes > Settings
- Firefox > History > Clear Recent History or Tools > Clear Recent History
If you use "Clear Recent History" to clear the cookies then Firefox also tries to clear the cookies from plugins like Flash (LSO) and starts a plugin-container process for each plugin and that can add extra time and can cause an unresponsive script error to appear.
Make sure that all plugins are up to date.
Exclude the cookies from "Clear Recent History" to see if that helps.
Let all cookies expire when you close Firefox to remove unwanted cookies and keep the ones with an allow exception.
Make sure that you do not clear the "Site Preferences" as that will remove all exceptions.
