I'm not really sure what it means. It says: Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.

See https://support.mozilla.com/kb/Could+not+initialize+the+browser+security+component

Rename secmod.db (secmod.db.old) in the Firefox Profile Folder in case there is a problem with the file.
You may have to rename cert8.db (cert8.db.old) as well.
Firefox will create new files.

The file cert8.db stores user certificates and intermediate certificates send by websites, so if you have certificates that you want to keep then you may want to export them now and import them after having removed cert8.db.
