If you've updated to Firefox 18 and it now crashes on startup it could be due to malware installed on your computer. We'll explain how to get rid of the malware which will let Firefox run normally.
Download and run Microsoft Safety Scanner
- Download Microsoft Safety Scanner
- When the program has finished downloading, open it and follow the instructions to start the scan. A "Full Scan" is recommended.
- Once the scan is complete the malware should be removed from your computer and Firefox will be able to start.
