Was that on a search site or what?

Suggest you watch your spelling or can be hit by malware.

Please Mark this as Solved, Thank You.

I went to type instagram.com in the URL box of FireFox but mistyped it. The edmunds truck site came up instead. No malware here. The norm is for my default search - Google - to present what it knows about what I mistyped.

Check to see if you have enabled or disabled search from the address bar. https://support.mozilla.org/en-US/kb/search-web-address-bar

If you made a the whole address including the .com Firefox is going to go to the site if it is a site and google has nothing to do with it.

Again watch your spelling, mistakes happen that can end up with malware.
