Alert! "Could not initialize the application's security component..."

Posted

I started getting this alert after a restart last Saturday (2-22-2014) and Thunderbird freezes before it is fully operational: (incorrect application behavior?)

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.

I have over 500 GB free on the hard disk and have checked the directory TTBOMA. As recently as this morning I again uninstalled TB using the TB uninstall utility, rebooted and reinstalled from the Mozilla website. Nada,

Toshiba Satellite L875D Windows 8

Troubleshooting info:

Thunderbird Version 24.3.0 User Agent Mozilla/5.0 (Windows NT 6.2; WOW64; rv:24.0) Gecko/20100101 Thunderbird/24.3.0

Any help out there?
