Problems with Firefox in 12.04

[JohnPta]

Hi there, I installed Ubuntu 12.04 and I can not use Firefox any more although it was working before. I did install addon's however.
When I start up Firefox I get this message.

"Could not initialise 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."

The HD has 132Gb free space.

I had to load Chromium to be able to post this message.

Hi,
there are many reasons for this but first try this.
got to your home folder click on view >show hidden files >look for the file .mozilla and delete it.

don't worry it will be recreated when you open FF again.
See if that cure the problem.

Impressive thanks it works again. Now I will start loading the "addonn's" again and I will see what happens.
