Did you delete the Firefox program folder ("C:\Program Files\Mozilla Firefox") ?)

Yes i deleted the Folder from Program files. Even i deleted from the %Application data. Still this did not help after fresh installation I also tried rhe latest 3.7 Beta version of Firefox, same issue. :(

Do a search for MOZCRT19.dll to see if there are other copies. You may also have to do a registry cleanup in case that file was registered incorrectly.

I have the same problem, mine started when Flash wanted to update, so i said ok, then once it took me to the installer, I changed my mind and cancelled. And then firefox the dll quit working. What does a registry cleanup do? MOZCRT19.dll only exists inside the Mozilla program files folder, so why would it randomly get corrupted or become un-registered?

This problem can be caused by malware.

Do a malware check with a few malware scan programs. You need to use all programs because each detects different malware. Make sure that you update each program to get the latest version of the database.

(you need the specific file that is part of your current Firefox installation - c)

Step1: Copy the downloaded file and paste it at the following location.

C: / Program Files / Mozilla Firefox

Note: C: It is the drive in which your windows is installed.

Step 2: After copy the file there, restart your windows.

With thousands of users experiencing this problem, why isn't Firefox creating a fix? Very poor judgement and terrible customer support.

Most forum fixes are junk! I turn off ZoneAlarm Pro, launch FF and immediately restart ZAP.

PIMA , fix it already!
