Both Firefox.exe & Firefox.exe.sig running in Win. Task Manager?
Should Firefox.exe.sig be running at the same time that Firefox.exe is running? Windows Task Manager showed me they were running separately at the same time. I had not noticed this happening before. What is Firefox.exe.sig?
Windows 7 32-bit Firefox Quantum 61.0.1

Hi, it is either a changed Firefox.exe file that was or thought was a virus by your A/V or it is part of a nightly build.
Did you recently do some changes, or have nightly installed or a beta ?
Please search for it and upload it to Virustotal.com difficult for me to say.
