Browser Inititation Bug

Binary package hint: mozilla-firefox

On attempting to load Firefox in Gutsy for the first time, the following error was given:

Could not initialize the browsers' security component. The most likely cause is a problem with files in your browser'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 browser and fix the problem.If you continue to use this browser session, you might see incorrect browser behavior when accessing security features.

This is output in terminal for 'firefox --p'

After opening, I deleted the old profile and created a new one. No errors occurred after this.
