Do you know a good adblocker to use on chrome?
uBlock Origin. Same as FF.

Shouldn't I be as worried/concerned since it appears that I only have a shortcut of the "firefox-patch.js" file and not the actual file?
If you only have the shortcut, then there's a good chance the actual files was deleted by your antivirus/antimalware already.
