Error message: Count not initialize the applications security component.....

I have been receiving the following error message when trying to access Firefox:
Could not initialize the applications security component. The most likely cause is problems with files in your applications 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 our continue to use this session you might see incorrect application behavior when accessing security features.
Firefox will not open any site. I am using a MacBook. The hard drive is not full. I recently had to start using a vpn to get remote access to my desktop at work. Then it wouldn't load so I had to install something to trick it into accepting the vpn. I do not recall what this was as I got this from a person at our helpdesk at work. I hadn't had any trouble for several days, then all of a sudden, Firefox won't open anything, no websites, no email, etc. I have been using Safari as so far it seems to be working. I do not wish to continue to use Safari and for portions of my job, I need to download things and using Firefox is the only browser that works with the software program I am using.
Can anyone help me with this problem?
Thank you very much.

Everytime I use firefox to connect to the internet I get an alert saying that firefox could not initialize the applications security component. What does this mean and how do I fix it?

When I use firefox to get on to the web I get the following message everytime: "Alert: Could not initialize the applications security component. The most likely cause is problems with files in your applications pforfile 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 feactures." Once I click the "OK button" at the bottom of the alert box firefox starts but does not act right. For instance it will not let me look for software updates. When I click on "Check for Updates" from the "Help" drop down menu I get a message stating: "There were problems checking for, downloading, or installing this update. Firefox could not be updated because: Update XML file malformed (200). You can update firefox manually by visiting this link and downloading the latest version."

On startup I get a warning "Could not initialize the application' security component...", click OK Firefox starts but I cannot navigate to any URL but home.

Click the Firefox 4 icon. A window opens with the warning:
"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"
(There are no read/write restrictions on my Applications folder and plenty of room on the hard drive.)
Click OK and Firefox opens at the home page, but I cannot navigate to any other URL or link. I had the same behavior when I tried FireFox 3)

First, use a specific [[Managing profiles|profile]] for Firefox 4.0 Beta and keep your current one for Firefox 3.6 to prevent interferences between both versions.
Then, see [[Could not initialize the browser security component]].

I keep getting the following error message: "Could not initialize the application's security component." Firefox then crashes when I try to enter a secure website. Help?

The exact error message is: "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.

I am on a MacBook and have been using Firefox for years without any problem until now.

Can you access other apps? Can you acess the internet? Can you access applications that use internet besides facebook?
If answer is yes to all of these; contact Facebook.

Firefox stopped working properly, it says it cannot initialize the applications security component...

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.

it then opens and will not let me click anything, just opens the homepage and stops, tried reinstalling and it still doesn't work.

Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

Hi,

"Could not initialize the application's security component" already erased mozilla directory containing profiles and the other in x86, problem persists!

This has just happened. But I have erased the mozilla directories containing the profiles and as well the both mozilla directories in program files x86. Yet when Firefoz is reinstalled, problem recurs.
Receive again the message "Could not initialize the application security component."
Have looked at the fixes available. Those appear not to work.
Anyone else with ideas? Maybe some hidden files that I can search for on my computer, and erase?
I'm suspecting I need really a thorough erase of anything connected with Firefox, to solve this issues. Thought though I had found everything.
Not relishing the prospect of erasing the hard-disc to fix this, though that has 100% probability of working.
My computer is running Wista 64.

Rename secmod.db (secmod.db.old) in the Firefox Profile Folder in case there is a problem with the file.
Firefox will create new files.
