malware

Hello,
I am new to this forum.
I made a purchase on ebay and downloaded 'package tracer' and 'my way' by mistake.
Can anybody tell me how to get rid of this junk from my firefox mozilla browser?
I have OSX version 10.9.5..Any help would be greatly appreciated!!

Welcome to the forum.

You can try malwarebytes from malwarebytes.com to see if it will remove them. You can also look at the extensions and see if they show up there for removal. I don't use FF, so I cannot give you exact steps to follow.
