I use Vista on my dell inspiron 1721. Firefox closed itself, computer shut itself down, a lot of 'corrupted files' were deleted without my interference, and when Vista finally came back up, Firefox wouldn't start. Nowit says I have to fix the firefox directory. How do I do that? The help page on the profile didn't help me. Thanks, mhixon This started when I was browsing on Drudge report. The popup message said: Could not initialize the application's security component. .... I could not start firefox again after that. How do I update a graphics driver?

Thank you for your reply. I did that and restarted the computer, but I am getting the same message- could not initialize the application's security component. And I am unable to get beyond the initial screen to get on any website. Anything else I can try? I appreciate the help.

You may need to delete the file secmode.db as well.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I found a file listed "secmod" without the e and without the extension, deleted that. Then I created an new profile. Now the security message doesn't come up, but I can't get to any website. I looked at my Kaspersky settings, but it no longer looks like the windows in the firefox help section on firewalls, so I am just over my head. I'll just use Chrome till I get a new computer! It is a sad day when the easiest way to fix a problem is to replace the thing.

I appreciate your  help though.
