This is not from the company Mozilla or the Firefox web browser.

edit: ok I see you are posting with a Mac OSX 10.10.5 as per more system details as below is more for Windows.


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

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

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista if you don't already have one. Windows 8/10 have antivirus protection built-in.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.
