Could not initialise the application's security component

When opening Firefox, I get a message "Could not initialise the application's security component. The most probable cause is problems with files in your browser's profile directory. Please check that this directory has no read/write restrictions and your hard drive 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 behaviour when accessing security features." Firefox then opens but all tabs are marked New Tab and no access can be obtained to the various websites. If I try to sign in to Google, a new window opens marked About:blank. I have wireless connection which is functioning correctly. Please help get my connection working if possible.

Thank you for this detailed explanation - I suspected the answer would be somewhere although I certainly had trouble locating it.
I haven't utilised this answer as I resurrected another laptop and copied folders from the AppData Local and Roaming folders and pasted them into my corrupted machine, which is now working well. However, I am extremely grateful to you for coming to my aid and have bookmarked the reply should it fail again.
I see someone else has the same problem, so your help will doubtless reach even further. Regards

I uninstalled the browser and download a new version but it does not resolve the issue.
I know my hard disc has ample space. I do NOT know where to find the Profile directory to fix the read restriction box.

Could not initialize the application's security component when clicking on a hyberlink from LotusNotes, default browser Firefox

I have Lotus Notes 8.5 installed on Windows 7 computer.
Firefox 4.0.1 works fine.
But when I change FF as default browser and launch a hyperlink from My mail client I get an error "Could not initialize the application's security component. The most likely cause is problems 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.

After this error I can open tabs but no website will work.
But if I close Firefox and reopen it will work.
When Firefox is running, if I click the hyberlink from my mail client, it launches without error message and works fine.
Gave Write access to profile folder. replaced cert8.db etc, but it is not helpful.
I installed Firefox 4 - same.
Installed Firefox 5 beta - same.
Installed Firefox 3.6.17 - error message is there but Firefox keeps working after launch.

In Mac OS X v10.7, the $HOME/Library folder is a hidden folder.
Open Finder and use one of these:
* Go > Go To Folder (Shift-Command-G) and in the dialog type: ~/Library
* Open the "Go" menu and hold down the Option key to make the Library appear
You can also use this command in a Terminal window to remove the hidden flag.
