"could not initialize the browser's security component" in Firefox

If you get the error "could not initialize the browser's security component" in Firefox, try these steps in order.

Note to get to your profile folder….
C:\Documents and Settings\user name\Application Data folder in Windows 2000 and XP or the C:\Users\user name\AppData\Roaming folder in Windows Vista

Hard drive capacity
Check your hard drive's remaining capacity. To do this on Windows machines:
1. Open My Computer
2. Right click on the C: drive
3. Choose Properties. A dialog will come up.
4. Go to the General tab
If it reports less than 1MB free space, you'll need to make more room.

File permissions
Check the file permissions in your profile folder. The file named cert8.db must not be read-only. To do this on Windows machines:
1. Open your profile folder in Windows Explorer.
2. Right click on the file named cert8.db.
3. Choose Properties. A dialog will come up.
4. Go to the General tab
5. Make sure the "Read-only" checkbox is not checked.
6. Press OK.

Corrupted file
The file cert8.db in your profile folder may have become corrupted. Delete this file while the application (Firefox, SeaMonkey, etc) is closed. To do this on Windows machines:
1. Close the application by choosing File -> Exit.
2. Open your profile folder in Windows Explorer.
3. Click on the file named cert8.db.
4. Press delete.
5. Restart the application. cert8.db will be recreated when you do so.

New profile
Create a new profile. Your current profile might be corrupted due to many reasons, such as changes in your system or lack of hard drive space at one point.
