What is your system and Firefox version?

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

Possible Mal-Ware Scan For Macs {web link}

Windows; You can try these free programs to scan for malware, which work with your existing antivirus software:

Those reports are no longer available.
